In this multi-part series, we'll explore how to build a modern, scalable pipeline for processing telecom Call Detail Records (CDRs) using Databricks Delta Live Tables. Part 1 focuses on the foundation: data generation and the bronze layer implementation. Telecommunications companies process billions of Call Detail Records (CDRs) daily. These records capture every interaction with the network—voice calls, text messages, data sessions, and more. Processing this data efficiently is critical for billing, network optimization, fraud detection, and customer experience management. In this series, we'll build a complete Telco CDR processing pipeline using Databricks Delta Live Tables (DLT). We'll follow the medallion architecture pattern, with bronze, silver, and gold layers that progressively ref…  ( 9 min )

Part 2 – Automating the Pipeline In Part 1 I wanted it to behave like a production-grade application: built, scanned, and deployed automatically with security woven into the process. This is the part where things got interesting — the pipeline. Let’s keep it real: my app is not a full-stack system. It’s a portfolio website — plain and simple. HTML for structure CSS for styling JavaScript for a little interactivity That’s it. But what made it special was how I treated it: I Dockerized it using an NGINX base image to serve static files. I pushed that image to AWS Elastic Container Registry (ECR). Then, I deployed it to Azure Container Apps using Terraform. Even though the app was static, the pipeline was dynamic. Here’s how the GitHub Actions workflow was designed: Checkout code from GitHub …  ( 8 min )

Let’s imagine something for a second. You're minding your own business, managing AWS infrastructure for a client with a pretty standard e-commerce setup: a Medusa.js backend, a Next.js storefront, and most importantly for this story, a PostgreSQL RDS instance safely stashed away in a private subnet where nothing from the outside world can touch it. Exactly how the AWS gods intended. Then, one day, your client says: "Hey, I need to get access to the production database" Now, there are plenty of legit reasons to want this kind of access: analytics, dashboards, audits, maybe some light database spelunking. In this case, it’s for Metabase, which as far as you can tell, magically turns SQL into colourful charts. So sure, let's help them out. You're a helpful DevOps engineer. You write Terraform…  ( 11 min )

Building a Distributed Background Job Scheduler with Redis and Node.js The Problem Complex workflows in distributed systems often require background processing that can take minutes to complete. Traditional vertical scaling approaches are cost-prohibitive due to low average utilization, while horizontal scaling introduces race conditions where multiple workers might process the same job. When designing distributed systems, we must balance the CAP theorem constraints: Consistency, Availability, and Partition tolerance. Leader-Follower Pattern: Maximum consistency through centralized job scheduling Complex implementation with single points of failure Unnecessary overhead for most use cases Leaderless Pattern (Recommended): Maximizes availability and partition tolerance Embraces …  ( 8 min )

🔹 Problem: 3021. Alice and Bob Playing Flower Game Difficulty: #Medium Tags: #Math, #Combinatorics Alice and Bob play a game with n flowers and m flowers. Each chooses one flower. Alice wins if the total number of petals is odd. You need to count the number of winning pairs (x, y) where 1 ≤ x ≤ n and 1 ≤ y ≤ m. Brute Force Idea: (x, y) and check if x + y is odd. That would be O(n * m), which is too slow for large inputs. Optimized Strategy: The solution was unexpectedly simple once I realized the parity logic: Alice wins only when one number is even and the other is odd. Count how many odds and evens are in 1..n and 1..m. odds_in_n = (n + 1) // 2 evens_in_n = n // 2 odds_in_m = (m + 1) // 2 evens_in_m = m // 2 Winning pairs = (odds_in_n * evens_in_m) + (evens_in_n * odds_in_m) Simplifies to (n * m) // 2. class Solution: def flowerGame(self, n: int, m: int) -> int: return (n * m) // 2 Time: O(1) Space: O(1) 🧩 Key Takeaways ✅ Learned how to reduce brute-force counting to simple parity logic. 💡 The trick is noticing that half of all pairs will have odd sums. 💭 In future, whenever I see problems about sums being odd/even, I’ll try counting odds and evens separately instead of brute force. [x] Could I solve this without help? [x] Did I write code from scratch? [x] Did I understand why it works?

RAG (Retrieval-Augmented Generation) is one of the most practical ways developers are applying LLMs today. Large Language Models (LLMs) are very good at writing and reasoning in natural language. But used naively, they come with three practical limits: Hallucinations: LLMs can make things up because they predict text by pattern-matching. Outdated knowledge: LLMs knowledge is frozen at training time, so they don’t know new events after their last update. Limited context window: LLMs can’t fit huge knowledge bases, like company wiki or long PDFs, into their limited prompt window, so they miss crucial details. Retrieval-Augmented Generation (RAG) solves these problems by pairing an LLM with a search layer. Let's unpack that... Information Retrieval is finding relevant data within large…  ( 9 min )

Hey DEV community! 👋 Like many of you, I have a habit—some might call it an obsession—of keeping up with the latest technology. My evenings are often spent browsing GitHub Trending, watching "new tool" roundups on YouTube, and checking out what's new on Hugging Face. The thrill of discovery is great, but it always leads to the same bottleneck: a mountain of README files. The real challenge isn't finding new projects; it's evaluating them quickly. I constantly ask myself: How steep is the learning curve? Is it practical for a real-world project? How much of a headache will it be to deploy? These questions aren't answered by star counts alone. I needed deeper insights, but I didn't have the time to investigate every single interesting repo. So, winding down last Friday evening here in Indon…  ( 8 min )

Introduction Machine learning has quickly moved from research labs into our everyday lives. It powers things like voice assistants, fraud detection systems, personalized shopping recommendations, and even medical diagnoses. At its core, machine learning is about teaching computers to learn patterns from data and make predictions without being explicitly programmed for every task. What Is Classification? Examples include: Is this email spam or not spam? Is this transaction fraudulent or legit? Is this image a cat, a dog, or a bird? Process of classification: Collect Data – Gather labeled examples. Preprocess – Clean the dataset (remove duplicates, handle missing values, etc.). Feature Selection – Pick the most relevant features. Model Training – Use an algorithm to learn from the labeled da…  ( 7 min )

Java Inheritance is a fundamental concept in OOP(Object-Oriented Programming). It is the mechanism in Java by which one class is allowed to inherit the features(fields and methods) of another class. In Java, Inheritance means creating new classes based on existing ones. A class that inherits from another class can reuse the methods and fields of that class types of inheritance Single Inheritance Multilevel Inheritance Hierarchical Inheritance Multiple Inheritance Hybrid Inheritance Single Inheritance class vehicle{ void bike() { System.out.println("bike comfort for two person"); } } class car extends vehicle { void red() { System.out.println("car comfort for four person"); } } public class Single { car c1 = new car (); c1.bike(); c1.red(); } } Output bike comfort for two person Multilevel Inheritance class vehicle{ void bike() { System.out.println("bike comfort for two person"); } } class car extends vehicle { void red() { System.out.println("car comfort for four person"); } } class bicycle extends car { void black () { System.out.println("i like so much"); } } public class Multilevel { public static void main(String args[]) { bicycle b1 = new bicycle(); b1.bike(); b1.red(); b1.black(); } } output bike comfort for two person Hierarchical Inheritance class vehicle{ void bike() { System.out.println("bike comfort for two person"); } } class car extends vehicle { void red() { System.out.println("car comfort for four person"); } } class van extends car { void white () { System.out.println("van comfort in more person"); } } public class Hierarchical { public static void main(String args[]) { van v1 = new van(); v1.bike(); v1.red(); v1.white(); } } output bike comfort for two person car comfort for four person van comfort in more person  ( 6 min )

There's a common sentiment in our web and mobile development world: "Do I really need Data Structures and Algorithms (DSA)? Isn't that just for MAANG interviews?" My experience says yes. I want to share a story from one of my projects where a fundamental understanding of DSA saved my day in production. I was working on an application where we managed invoice payments. We had a specific, real-world optimisation problem: "Given a fixed pool of cash, how do we pay as many outstanding invoices as possible to maximise the total amount paid, without exceeding the available cash?" Sounds like a fairly standard business requirement, right? At first glance, one might start thinking about complex loops, sorting strategies, or even greedy approaches.

When working with data structures in Java, two of the most commonly used classes are ArrayList and LinkedList. Both are part of the java.util package and implement the List interface, which means they share many common methods. However, the way they work internally is different, and this difference makes each one suitable for different use cases. Based on Dynamic Array Fast Access (O(1)) Slow Insertion/Deletion Memory Usage Best Use Case searching and accessing elements is frequent. LinkedList Based on Doubly Linked Nodes Slow Access (O(n)) Fast Insertion/Deletion Memory Usage Best Use Case Side-by-Side Comparison Feature ArrayList (Dynamic Array) LinkedList (Doubly Linked List) Storage Dynamic Array Doubly Linked Nodes Access (Read) Fast – O(1) Slow – O(n) Insertion/Deletion Slow (shifting needed) Fast (update node links) Memory Less (stores only data) More (data + next + previous references) Best For Searching & frequent access Frequent insertions & deletions Apart from the common List methods, LinkedList provides some additional methods: addFirst() – Add element at the beginning addLast() – Add element at the end getFirst() – Retrieve first element getLast() – Retrieve last element removeFirst() – Remove first element removeLast() – Remove last element  ( 6 min )

When deploying applications in Google Cloud Platform (GCP), managing virtual machines (VMs) individually can become complex and inefficient. That’s where Instance Groups come into play. An Instance Group is simply a collection of VM instances that you manage as a single logical unit. This allows you to scale, load balance, and automate lifecycle management of multiple VMs easily. GCP offers two main types of instance groups: 1️⃣ Unmanaged Instance Groups Can contain non-identical VMs (different machine types, OS images, or configurations). Example: A mix of e2-small and e2-micro VMs. Supports load balancing, but lacks advanced features like: Autoscaling Auto-healing Auto-updating Multi-zone deployments Instance Template not required. ⚠️ Not recommended unless you specifically need to run d…  ( 6 min )

Docker has become a must-have tool for modern software development. Whether you’re building web apps, APIs, or microservices, Docker makes it easier to package, ship, and run applications in a consistent way. If you’re new to Docker, here’s a simple beginner-friendly guide to get you started. Docker is a platform that lets you run applications inside containers. Consistency → Works the same on your machine, staging, and production. Portability → Run anywhere (Linux, Windows, macOS, cloud). Isolation → No more "it works on my machine" issues. Efficiency → Faster and lighter than full virtual machines. Image → A snapshot/template of your app. Container → A running instance of an image. Dockerfile → Instructions for building an image. Docker Hub → A public registry for Docker images. # Check Docker version docker --version # Run a container docker run hello-world # List running containers docker ps # Stop a container docker stop # Remove a container docker rm docker run -d -p 8080:80 nginx ➡️ Visit http://localhost:8080 and you’ll see the Nginx welcome page. # Use Node.js base image FROM node:16 # Set working directory WORKDIR /app # Copy project files COPY . . # Install dependencies RUN npm install # Start the app CMD ["npm", "start"] Then build and run: docker build -t my-app . docker run -p 3000:3000 my-app Docker helps developers build and deploy apps faster, with fewer headaches. By learning the basics of images, containers, and Dockerfiles, you’re already on your way to mastering containerized development. 💬 Have you started using Docker yet?

Introduction In today’s world, developers are bombarded with tutorials, docs, blog posts, Stack Overflow answers, GitHub issues, conference talks, and random tweets. The problem isn’t the lack of information—it’s how to organize and retrieve it when you actually need it. That’s where the idea of a Second Brain comes in—a system to store, organize, and recall technical knowledge outside your head. You learn a cool Linux command but forget it in a week. You copy a SQL query but don’t remember the optimization trick later. You read about clean architecture, but when you start a new project, you can’t recall the details. creativity and problem-solving.

When you use a CDN, cached copies of your website’s static assets are stored at the network edge for fast delivery to your visitors. Well, if your website is just those assets, why not just dump the whole thing at the edge and serve it directly from there instead of storing it on a web hosting service in the first place? That's what the JavaScript Static Publisher for Fastly Compute does. It delivers your static site straight from the network edge using a serverless app to handle user requests, and an edge data store for your content. This kind of originless setup is well suited to generated static sites made up of HTML, CSS, and client side JavaScript, like blogs and react apps.

And how it can save you thousands in infrastructure costs while you sleep Remember that sinking feeling when your side project suddenly got featured on Product Hunt and your $5/month server crashed spectacularly? Yeah, we've all been there. Last year, I watched a friend's brilliant SaaS idea crumble under unexpected traffic because they built it on traditional infrastructure. The irony? The very success they'd dreamed of became their downfall. But what if I told you there's an architecture that scales automatically, charges you only for what you use, and can handle traffic spikes without breaking a sweat? Enter serverless architecture – the paradigm shift that's quietly revolutionizing how we build SaaS applications. Despite its name, serverless doesn't mean "no servers." It means you don…  ( 9 min )

In 2025, super apps are no longer a niche concept confined to Asia—they are a global trend reshaping digital markets. From Southeast Asia’s Grab and Indonesia’s Gojek to Latin America’s Rappi and Africa’s M-Pesa-driven ecosystems, the model of combining multiple services under a single digital roof has become a competitive standard. Yet with this rise comes scrutiny. Policymakers, regulators, and even consumer advocacy groups are increasingly questioning the implications of super apps on competition, privacy, and financial stability. As the ecosystem matures, the challenges facing these platforms may be as defining as their opportunities. Super apps concentrate data, services, and financial flows in unprecedented ways.

Solving the Classic Two Sum Problem (FAANG-Style) One of the most common problems that shows up in coding interviews—especially at FAANG-level companies—is the Two Sum problem. It’s simple at first glance, but it gives interviewers a window into how you approach problem-solving, trade-offs, and optimization. Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution. You cannot use the same element twice. You can return the answer in any order. Example 1: Input: nums = [2,7,11,15], target = 9 Output: [0,1] Example 2: Input: nums = [3,2,4], target = 6 Output: [1,2] Example 3: Input: nums = [3,3], target = 6 Output: [0,1] Constraints: 2 <= nums.length <= 10^4 -10…  ( 7 min )

One of the most common challenges for automation engineers using JavaScript/TypeScript is handling asynchronous code. Whether you’re writing tests in Playwright or Cypress, you’ll often deal with actions that don’t resolve instantly — such as page navigation, element interactions, or API calls. That’s where Promises, async, and await come in. Let’s break them down with automation-specific examples. What is a Promise? A Promise represents the eventual completion (or failure) of an asynchronous operation. Think of it like a “contract” — “I’ll give you the data when it’s ready.” Example: Fetching Data const dataPromise = fetch('https://api.github.com/users'); dataPromise.then(response => response.json()) .then(data => console.log(data)); In test automation, every browser action i…  ( 7 min )

For over two decades, Robert C. Martin’s S.O.L.I.D. principles have served as the North Star for every serious developer. We study them, we discuss them in interviews, and we strive to apply them in our code. But there’s a problem. S.O.L.I.D. is a “gentleman’s agreement.” It’s a philosophy that lives in the minds of architects and on the pages of books, but remains almost invisible in the code itself. How can you prove that your code truly adheres to the Single Responsibility Principle? How can you ensure a new team member won’t violate the Dependency Inversion Principle? Until now, the answer has always been: “Trust in code reviews and the experience of your team.” That answer is now obsolete. We’re used to thinking of S.O.L.I.D. as the foundation and our code as the building. But we’ve n…  ( 7 min )

My Summer Internship: Building Two Full-Stack Projects with Python and Flask My summer internship at Techmicra IT Solutions in Ahmedabad, Gujarat, was a deep dive into the world of full-stack development, and I’m excited to share my experience. Over five weeks, I went from theory to practice, building two data-driven web applications that brought my B.Tech. studies in Artificial Intelligence and Machine Learning to life. My goal was to apply my Python skills to real-world problems, with a focus on API integration, data processing, and backend development.

This was my first major project, a web-based application to track live stock price…  ( 7 min )

My journey took an exciting turn when I discovered several tools that significantly accelerated my development process. I adopted what I call "vibe coding" - a development philosophy that prioritizes maintaining momentum and a positive mindset while coding. Rather than getting stuck in analysis paralysis, I focused on writing code that felt right and solved problems efficiently, even if it wasn't perfect. This approach helped me stay motivated and make consistent progress, especially during challenging phases of development. One of the game-changers in my development journey was using Cursor, an AI-powered code editor. With Cursor: I could describe functionality in plain English and get code suggestions Debugging became more intuitive with AI-assisted error analysis I learned new programmi…  ( 7 min )

You know the feeling. Your customer support queue is exploding, your CSAT scores are plummeting, and your old rule-based chatbot is about as useful as a screen door on a submarine. It can parrot pre-written answers, but the moment a customer has a complex, multi-step problem—it fails. Spectacularly. This was the exact reality for "GlobalEcom" (a fictional name for a very real problem we solved). Their growth had outpaced their support infrastructure. They didn't need a better chatbot; they needed an intelligent AI agent that could reason, take action, and learn. And it needed to be built to scale. This is the story of how we architected that solution on AWS, creating a system that not only handled a 300% surge in queries but did so while reducing costs and improving resolution rates.

Vaadin has always been a bit different. Yes, it's a Java framework. Yes, it’s great for building modern web UIs. But if you’ve ever used Vaadin seriously, you’ve probably noticed something that sets it apart: its component architecture. Whether you're using a ready-made component from the official library, building your own from scratch, or integrating a 3rd-party NPM package, all Vaadin components follow a consistent maintainable structure that bridges the server and the client and can evolve along with your application. There are lots of UI libraries out there. React has its components. Lit has web components. Bootstrap has... buttons. Vaadin? It’s not just about visuals. It is not uncommon that Vaadin application and components are developed and maintained for many years. That is by d…  ( 8 min )

Light and dark themes have been around for a while, but there is still no way to configure them in PWAs. Or rather, there is no standard at the manifest level: I found a solution to overcome this limitation. It follows the conventions, even though we aren’t going to use the manifest. Unfortunately, manifests are static JSON-formatted files which can’t change on user input. This means that they can only provide a theme_color key at a time: there’s no chance to make it dynamic. So, what if you want to support both light and dark themes? You have to choose between the two. Ish. You can use a combination of CSS and JavaScript to let users set their own preferred theme, but you can’t change the theme_color accordingly—not from the manifest, at least. All is not lost! You can always choose not t…  ( 7 min )

We are living in the golden age of AI assistants. They write code, find bugs, and refactor entire modules. But they have a fatal flaw that turns any complex project into a swamp. That flaw is contextual amnesia. Human ↔ Human Communication The Problem: A new developer spends weeks just to get up to speed. Key project knowledge is stored in the minds of veterans and is lost when they leave. The Solution with AOKL: A developer opens any file and, within 30 seconds, gets answers to the most important questions: What is this file for? What is its place in the architecture? What is it connected to? AOKL becomes the universal, always-current source of truth. Human ↔ AI Communication The Problem: The infamous "contextual amnesia." Endless iterations in prompts. The Solution with AOKL: Instead of asking, "fix this bug, but remember that this module works with Stripe payments...", you simply provide the code with an AOKL block: code Aokl /** @PURPOSE: Processing transactions via the Stripe API. @INTEGRATION: User_Profile_API, Billing_DB. */ For the AI, this is no longer a request. It's a comprehensive technical spec. AI ↔ AI Communication The Problem: Today’s AI agents are incapable of collaborating effectively. The Solution with AOKL: AOKL becomes the lingua franca that allows a swarm of AI agents (Architect, Coder, Refactorer, Tester) to work together seamlessly on a single project. Conclusion We stand at the dawn of a new era, where a developer's value is defined by their ability to clearly articulate architectural intent. AOKL is the tool for this new era. It transforms an AI assistant from a "helper" into a true "partner" and lays the foundation for future autonomous development systems.  ( 7 min )

When building an API in Go, you may notice you keep writing this kind of code everywhere: if email == "" { validationError := responses.Response{ Code: 422, Message: "Invalid email", } w.WriteHeader(http.StatusUnprocessableEntity) json.NewEncoder(w).Encode(validationError) return } This gets repetitive, messy, and hard to manage as your project grows.

“In today’s world, your code might get you noticed… but your brand will get you remembered.” Not too long ago, I met a brilliant developer—we’ll call him Tunde. His GitHub was full of innovative projects: clean code, unique solutions, and well-documented repositories. Yet, he often complained, “No one seems to notice what I build.” The problem wasn’t his skill. It was visibility. A few months later, Tunde started doing something different: He shared short tutorials on LinkedIn. He posted Twitter/X threads about debugging lessons. He wrote a blog post explaining how he optimized an API. The result? Recruiters reached out, other devs engaged with his content, and he even got invited to speak at a local tech meetup. 👉 The lesson?

We, the architects of digital worlds, are drowning. We are drowning in “swamp” of low throughput — not between servers, but between intellectual entities: human and AI, and even human and human. I, Vladimir Igorevich Evpolov, drowned in this swamp while working on one of the most complex B2B projects of my 18-year career. My AI partner suffered from “contextual amnesia.”. Each new request was like a new day. And I turned from an architect into a nanny for a genius. Efficiency tended to zero, slowing down the entire process AI development. Press enter or click to view image in full size The problem goes deeper. How many hours were wasted because a new developer on the team didn’t understand the “unwritten” intentions of the old one? Our most valuable asset, the architectural concept, is lost with every transmission. We communicate at the speed of speech, while machines communicate at the speed of light. It was to solve this problem that the protocol was created. Architecture-oriented commenting (AOC). What is Architecture Oriented Commenting (AOC)? Basic Principles of the AOC: @file: File name. The world is looking to Elon Musk’s neural implants as a solution. It’s a “brute force” approach: an attempt to directly connect our biological brains to a machine. But it’s risky, expensive, and, for most, scary. I believe the answer lies not in risky surgery, but in elegant engineeringWe shouldn’t change the person. We should improve the language we communicate through code. AOK is our first step towards creating a future where AI development will not be slow and painful, but fast, effective and limitless.

In software development, how we structure applications significantly impacts scalability, maintainability, and deployment. Traditionally, applications followed a monolithic architecture, but as systems grow complex, microservices offer a more flexible alternative. Let’s explore the basics. What is a Monolithic Architecture? In a monolithic architecture, all features—like authentication, payments, orders, and shipping—are bundled into one large codebase. This works for small applications but poses challenges for larger systems: Single Point of Failure: If one module (e.g., inventory) fails, the entire app can crash. Scaling Issues: Scaling one feature means scaling the whole system, which is inefficient. Risky Deployments: A single bad update can break the entire application. For exa…  ( 6 min )

When working with Angular, you’ve probably noticed that your development server often runs on localhost:4200. But what does this really mean, and why is it important for your development workflow? In simple terms, localhost refers to your own computer, typically mapped to the IP address 127.0.0.1. The number 4200 is the default port chosen by the Angular team for the development server. When you see http://localhost:4200/ in your browser, it means an Angular application is running locally in development mode. This setup allows you to see live changes in your application as you work, thanks to features like live reload and hot module replacement. The choice of port 4200 wasn’t random, it was selected to minimize conflicts with other common ports used by development tools. When you run comma…  ( 7 min )

If you use Windows daily, chances are you rely on screenshots more than you realize. Microsoft’s built-in Snipping Tool works in a pinch, but when you need speed, polish, and flexibility, it starts to fall short. That’s why I built Snipper — a lightweight screenshot app for Windows designed for developers, creators, and anyone who wants more control over their captures. Snipper is a lean Windows Snipping Tool alternative whose focus is to take screenshots fast and make them look 10X more beautiful. All that in seconds!

If you’ve ever configured a Wi-Fi router or set up a server, you’ve probably stumbled across something like 255.255.255.0. That strange number is a subnet mask — and it plays a crucial role in how devices know whether they should talk directly to each other or send data through a router. Let’s break it down in simple terms. Every device on a network has an IP address, and that address has two parts: Network part → Identifies which network the device belongs to Host part → Identifies the specific device inside that network Example: 192.168.1.42 192.168.1 = Network part 42 = Host part But how do we know where the split happens? That’s where the subnet mask comes in. A subnet mask tells a device which portion of the IP address is for the network and which portion is for the ho…  ( 7 min )

If you’ve been tracking PC hardware prices lately, you may have noticed something puzzling: the price of DDR4 RAM is rising — even though it’s no longer the latest memory standard on the market. With DDR5 now more widely available, logic would suggest that older DDR4 modules should become cheaper. So why is the opposite happening? This article explores the key reasons behind the increasing prices of DDR4 RAM and offers insights into the market forces and industry decisions driving this trend. Whether you’re a PC builder, gamer, system integrator, or simply curious about tech economics, this blog will give you a clear and in-depth understanding of the situation. The most fundamental reason behind rising DDR4 prices is the industry-wide shift to DDR5. As more consumers and businesses adopt n…  ( 8 min )

In the era of remote work, hybrid infrastructure and cloud solutions, a reliable and secure connection to corporate resources is not just a wish, but a mandatory requirement. Especially when it comes to accessing data and services located in a data center. Today we will figure out which methods of secure connection to a data center are relevant in 2025, and how technologies such as IPSec VPN, WireGuard, SSL VPN and others differ from each other. 📡 Why do you need a secure channel at all? Connecting to a data center without encryption is a direct risk of data interception, MITM attacks and infrastructure compromise. Especially if employees, partners or services connect from outside, via the Internet. An encrypted tunnel provides: Confidentiality (data is not read in transit) Integrity (i…  ( 7 min )

Routers and Route Tables: The GPS of the Internet When you send an email, stream a video, or open a website, your data doesn’t travel in a straight line. Instead, it jumps from network to network, guided by one of the most important devices on the internet: the router. Routers are like the GPS of the digital world, ensuring every packet of data finds its way across the vast highways of the internet. And the secret to their intelligence lies in something called the route table. A router sits at Layer 3 of the OSI Model — the Network Layer. Its job: move data between different networks. While a switch connects devices inside a local network (LAN), a router is the bridge that connects one LAN to another — and eventually to the internet. Every router has one or more network interfaces …  ( 7 min )

If you’ve ever felt like the SOLID principles sound too abstract, don’t worry; in this article we’ll break them down into simple, relatable examples with analogies. By the end, you’ll understand each one in a way you’ll never forget. Let’s dive in! 1. Single Responsibility Principle (SRP) Each app does one job well. If your camera app also tried to send messages and play music, it would become messy and hard to maintain. In code terms, this means: ❌ Don’t do this: ✅ Do this: Each class does one thing well, making it easier to maintain, test, and reuse. 2. Open/Closed Principle (OCP) This means classes should be open for extension but closed for modification. In the sense that you should be able to add new features without changing existing code. Example: Now, if you want to add PayPal, …  ( 8 min )

To build great products, start by listening. Everything matters. Every bug report, feature request, or glowing review. These are the signals that fuel your product roadmap. However, standing between success and failure is the pain of managing and routing that feedback to the right teams. According to a Zendesk report, 59% of support teams are overwhelmed. Feedback pours in from multiple channels, often causing delays and leaving users feeling ignored. Support teams want to help; they try to, but the fragmented channels jeopardize their efforts. When this happens, nobody wins. What if feedback didn’t float around in limbo or reside in silos but instead went straight to the people who can fix the problem—right inside Slack.

When you first install WordPress, everything feels simple: a fresh site, a dashboard that looks clean, and endless possibilities. But it doesn’t take long before small mistakes pile up and make the site harder to maintain, slower to load, or even insecure. After more than a decade working as a freelance WordPress developer, these are the basic mistakes I see over and over again — and how to avoid them. The WordPress ecosystem is full of plugins. Many of them are useful, but too many create problems. Every plugin adds extra code, extra database queries, and a higher chance of conflicts. A better habit is to keep a core stack of trusted plugins and learn them deeply instead of installing new ones for every task. For example, I work mainly with Elementor Pro, JetEngine, WP Rocket and Fl…  ( 7 min )

In modern software delivery, containerization has become the de-facto standard for packaging and deploying applications. While Docker Hub is widely used, many organizations rely on private registries (Harbor, Nexus, Artifactory, AWS ECR, Azure ACR, Google GCR, etc.) to securely host and distribute container images. This blog walks you step-by-step through the process of creating a project locally, building a Docker image, and pushing it directly to a private Docker repository. Before you begin, ensure you have: Docker installed on your local machine. Access to a private registry (credentials + URL). A project to containerize (we’ll use a Java Spring Boot example here). Let’s assume you have a Spring Boot application. Build it locally: mvn clean package -DskipTests This will generate an ex…  ( 7 min )

JWT Best Practices and Pitfalls: A Comprehensive Guide Introduction: JSON Web Tokens (JWTs) have become a cornerstone of modern web application security, enabling secure and stateless authentication and authorization. They provide a compact and self-contained way for securely transmitting information between parties as a JSON object. However, JWTs are not a magic bullet, and improper implementation can lead to serious security vulnerabilities. This article aims to explore best practices for using JWTs effectively, while also highlighting common pitfalls that developers should avoid. Prerequisites: A basic understanding of the following concepts is helpful before diving into JWT best practices: Authentication: Verifying the identity of a user.

Traditionally, containerizing a Java application requires writing a Dockerfile, building an image with Docker, and then pushing it to a registry. While effective, this approach introduces extra steps and dependencies. Google Jib eliminates that complexity. It integrates directly into your build tool (Maven or Gradle), allowing you to build and push container images straight from your Java project — no Dockerfile, no docker build, and not even Docker itself on your machine. No Docker daemon required (works even if Docker isn’t installed). Build directly from Maven/Gradle (seamless developer experience). Layered image caching for faster incremental builds. Optimized images with minimal overhead. Add the plugin to your pom.xml: com.google.cloud.tools <artifactI…  ( 7 min )

Introduction Automating user interfaces has come a long way—but there are still situations where traditional methods fall flat. One of the biggest challenges arises when working with canvas-based applications, where no DOM elements exist for key interactive components. This makes it nearly impossible for standard test frameworks to simulate interactions like clicks, taps, or hovers using selectors alone. This blog post introduces a novel solution to this problem: the wdio-visual-click-service, a new plugin for WebdriverIO that allows test scripts to interact with UI components using image matching instead of DOM queries. In modern UI automation, developers and software engineers in test often run into limitations when trying to interact with components that don’t expose reliable DOM sele…  ( 10 min )

"Back to school" is here... (at least in France), but have you ever tried to fit a whole school into an Excel file? 🤔😄 While the question seems strange, this is exactly what an ORM (Object-Relational Mapping) aims to do. Imagine you're a principal and you have to enter all the students, their parents, teachers, subjects, classes, etc., and most importantly, all the relationships that link them, into your spreadsheet. It's quite a puzzle! If we were to create an application to help our principal, the ORM would be there to help us distribute these concepts (student, parent, teachers...) into the sheets of the Excel file (more specifically, into the tables of the database). It would then allow us to access them to find out if H.Potter has a Math class on Tuesday from 2 p.m. to 3 p.m., or to…  ( 6 min )

I am kind of ranting here so Je suis désolé... This year was kind of rough on me, both the year and me. I graduated in May 15 of this year. Commuting to college, going to the gym , meal prep, taking care of sick grandma , assignments , exam preps, getting 20 k steps a day consumed all of my attention and time. Plus my social media doom scrolling didn't help. As a wise man once said "The chains of habit are too light to be felt until they are too heavy to be broken" . I am the living example of that. It is very easy to let go of discipline, routine that makes someone great. When chaos or entropy eventually gets in the way of your idealized version of life, do you persevere or quit, and that is the deciding factor. Moving on I think it's my responsibility to rise above the hurt and chaos. I owe it to my future self, I am worth it. If you read this I am very grateful.  ( 6 min )

AI startups are everywhere right now. New tools, new APIs, new venture rounds. But if you zoom out, the survival rate isn’t very encouraging. Most AI startups fail within a few years, not because of lack of hype, but because they couldn’t translate cool demos into sustainable businesses. Here are a few notable cases, what went wrong, and the takeaways for developers and builders. MetaMind wanted to bring deep learning as an easy service for businesses. Backed by big names like Marc Andreessen, it was later acquired by Salesforce and folded into Einstein AI. Problem: Tech differentiation was weak.

Imagine this: What happened? Cold Starts in serverless computing. They’re invisible to most developers until they strike—and when they do, performance takes a hit. In serverless architectures (like AWS Lambda, Azure Functions, Google Cloud Functions), your code doesn’t run continuously. Instead: The provider spins up a new container to run your function. This initialization process adds extra latency. That delay = a “Cold Start.” If your function has been inactive for a while, the next request will likely hit a cold start. Cold starts might sound harmless, but they can silently kill user experience: ❌ Higher response times for the first request. ❌ Poor experience in latency-sensitive apps (chat, payments, APIs). ❌ Frustrated users → higher bounce rates. Real talk: Even a 1-second delay ca…  ( 7 min )

API ইন্টিগ্রেশন করতে গিয়ে কি কখনো মনে হয়েছে, "ধুর, এর চেয়ে তো ম্যানুয়াল কাজ করাও ভালো ছিল!"? আমরা যখন নতুন কোনো সার্ভিস বা পেমেন্ট গেটওয়ে ইন্টিগ্রেট করি, তখন সবচেয়ে বড় চ্যালেঞ্জ হয় documentation। অসম্পূর্ণ বা confusing documentation, inconsistent response format, আর হঠাৎ করে আসা error—সব মিলিয়ে মাথা খারাপ হওয়ার জোগাড়। আমি এই চ্যালেঞ্জগুলো তিনটি ধাপে মোকাবিলা করি: ১. প্রথমে ডকুমেন্টেশন পড়া: কোনো কোড লেখার আগে API-এর ডকুমেন্টেশনটা ভালো করে পড়ে নেই। কোন endpoint কী কাজ করে, কোন parameters পাঠাতে হবে, আর response কেমন আসবে—এগুলো ভালোভাবে বোঝার চেষ্টা করি। ২. Postman দিয়ে টেস্টিং: সরাসরি কোডে হাত না দিয়ে প্রথমে Postman-এর মতো টুল ব্যবহার করে প্রতিটি endpoint টেস্ট করে নেই। এতে করে authentication, request format আর error handling-এর ব্যাপারটা পরিষ্কার হয়ে যায়। ৩. সুন্দর Error Handling: এরপর যখন কোডে API কল করি, তখন শুধু happy path নিয়ে ভাবি না, একই সাথে error handling-এর জন্য একটি robust mechanism তৈরি করি। যেমন, যদি কোনো কারণে API downtime-এ থাকে বা unexpected response পাঠায়, তখন যেন অ্যাপ্লিকেশন ক্র্যাশ না করে, বরং ইউজারকে একটি সুন্দর মেসেজ দেখাতে পারে। আপনার সবচেয়ে চ্যালেঞ্জিং API ইন্টিগ্রেশনের অভিজ্ঞতা কোনটা ছিল? কোন API আপনাকে সবচেয়ে বেশি ভুগিয়েছে? কমেন্টে আপনার অভিজ্ঞতা শেয়ার করুন!  ( 6 min )

The CAP theorem, introduced by Eric Brewer in 2000, helps us understand the limitations of distributed systems. It says: 👉 In a distributed system, you can only choose 2 out of 3 properties at the same time: Consistency (C) Availability (A) Partition Tolerance (P) You cannot have all three at once. Meaning: Every read gets the latest written data (or an error if not possible). Analogy: Imagine you update your WhatsApp profile picture. If your friend checks it, they should see the latest photo immediately. Real-World Example: In banking systems, if you transfer $100 from your account, the system must instantly update the balance everywhere. Otherwise, you could withdraw money twice.

After explaining Kubernetes in simple terms, many have asked about service meshes, particularly Istio. So let’s dive into Istio, a powerful service mesh that helps manage, secure, and observe microservices in a Kubernetes environment. If Kubernetes is like a global restaurant franchise, Istio is like the traffic control and security system of a bustling smart city filled with tons of little shops, roads, and delivery trucks all needing to communicate reliably and securely. Imagine your collection of microservices as vibrant businesses spread across this city, each handling its own specific job. Some sell bread, others deliver packages, some offer repairs, it’s a complex ecosystem that needs order to thrive. Without a city planner, traffic controller, and security patrols, this city becomes…  ( 10 min )

Si vous souhaitez le lire en ANGLAIS, cliquez ici : Version Anglaise De nos jours, les PME et les grandes entreprises se précipitent pour intégrer l'IA dans leurs sociétés afin d'améliorer leur productivité ou tout autre aspect nécessaire.

Everyone's talking about Google's Guardrailed-AMIE, but the real shift isn't the AI—it's how doctors and machines team up for safer, faster care. Most AI in healthcare promises speed and misses trust. Patients and clinicians need both. The winners will design for safety, workflow, and proof. Google's Guardrailed-AMIE points to a better pattern. Multi-agent AI interviews patients, drafts a structured note, and flags uncertainty. Then a physician reviews, edits, and approves before anything goes back to you. That sequence builds accountability, auditability, and real adoption. When humans stay in the loop, risk drops and ROI goes up. Picture a mid-size clinic testing this for intake and triage. In month one, average intake time drops from 12 minutes to 8. Clinicians recover 10 hours a week, and patient wait times shrink 18%. Every answer includes sources and a clear record of who approved it. ↓ The Human-Guarded AI Playbook. • Start with one high-friction flow: intake, FAQs, or refills. • Map risks and escalation paths, then set physician gate checks. • Capture structured data, sources, and edits for an audit trail. • Ship patient-facing language at an 8th grade reading level. ↳ Launch in 90 days: pilot one team, measure time saved, expand stepwise. ⚡ Faster visits, fewer errors, higher trust. ⚡ Leaders get scale without burning out clinicians. Have you seen human-in-the-loop AI work in your org, or what's stopping you?  ( 6 min )

1️⃣ Introduction Agent-to-Agent (A2A) Protocol is an open standard that enables independent AI agents to discover each other, share capabilities, and collaborate on tasks in a secure and interoperable way. Instead of building one monolithic agent, A2A allows specialized agents—such as a planner, researcher, or executor—to communicate seamlessly across different frameworks and organizations. By defining a common structure for discovery (Agent Cards), task management (Task lifecycle), and communication (messages & parts), A2A provides the foundation for scalable, multi-agent ecosystems where agents can work together much like microservices do in modern software architectures. A small, self-describing JSON document that advertises an agent’s identity, capabilities, and how to interact with …  ( 9 min )

When deploying compute workloads in Google Cloud, you generally choose between Persistent Disks (PDs) and Local SSDs. Persistent Disks: Durable, network-attached, can be resized, backed up with snapshots, and survive VM reboots. Local SSDs: Physically attached to the host, extremely fast (high IOPS & throughput), but ephemeral – data does not persist if the VM is deleted (unless explicitly preserved during stop). In this tutorial, we’ll walk through how to: Create a VM with a Local SSD Format and mount the SSD Configure auto-mount after reboot Test persistence across reboots and stops Clean up resources 👉 From the Console: Go to Compute Engine → VM Instances → Create Instance Name: demo9-vm-localssd Region: us-central1 Zone: us-central1-a Machine family: N2 (not all series support Local S…  ( 7 min )

Histogram in R How to create histograms in R To start off with analysis on any data set, we plot histograms. Knowing the data set involves details about the distribution of the data and histogram is the most obvious way to understand it. Besides being a visual representation in an intuitive manner. It gives an overview of how the values are spread. We come across many depictions of data using histograms in our day to day life. For example, the distribution of marks in a class can be best represented using a histogram and so does the age distribution in an organization. The good thing about histograms is that it can visualize a large amount of data in a single figure and convey lots of information. It is quite easy to spot the median and mode by looking at histograms. A histogr…  ( 12 min )

If you’ve played with AI image tools, you probably know the frustration: sometimes you type something simple and the result looks nothing like what you imagined 😅. That’s where** ***prompt engineering* comes in. It sounds fancy, but honestly, it’s just learning how to give AI the right instructions so you get better results. Think of AI like a waiter at a restaurant 🍽️. If you just say,** “I want food,” you might get something random. But if you say, **“I’d like a cheeseburger with extra cheese, no onions, and crispy fries on the side,” you’re way more likely to get exactly what you want. Prompt engineering works the same way — the clearer your prompt, the better the image. Be Clear, Be Specific ❌ “Dog in park” Mention Style or Vibe Want it to look like a painting, 3D art, or a cartoon? Just say it. Play with Mood & Lighting Lighting changes everything! Add Camera or Art References 👉 “Landscape of snowy mountains, wide-angle lens, sunrise, National Geographic style” Experiment, Don’t Stop at One Your first prompt won’t always be perfect. Tweak words, change the order, and see what happens. AI responds well to trial and error. Here’s a simple formula I use for almost every prompt: [Subject] + [Action] + [Details] + [Style/Lighting/Camera] 👉 Example: Saves you time (no endless re-generating) Makes your images look more professional Gives you more creative control instead of leaving it all to chance Prompt engineering isn’t some “expert-only” skill. It’s just practice. The more you play around with your prompts, the more natural it feels — and the better your AI images get. So next time, don’t just type** **“dog in park.” Add a little extra detail, throw in a style, mention the vibe you’re going for, and watch the magic happen ✨. At the end of the day, it’s not about the AI. It’s about how** **you talk to it. 🔥 If this helped, share it with a friend who’s also messing around with AI art. Trust me, they’ll thank you later!  ( 7 min )

When you interact with Large Language Models (LLMs) like GPT-5, LLaMA, or Claude, it feels like you’re sending sentences and paragraphs. But under the hood, the model doesn’t “see” text the way we do. Instead, everything you type is broken down into tokens—tiny units that sit at the heart of how LLMs process, generate, and price their outputs. In this post, we’ll dive deep into tokenization in machine learning, why it matters for developers, and how you can actually experiment with tokenizers using tools like tiktokenizer. Tokenization is the process of splitting text into smaller units called tokens, which are then mapped to numerical IDs and embedded into vectors for processing. For us, words are natural chunks of meaning. raw text and mathematical computation. Example (GPT-style tokeniz…  ( 7 min )

Di Ceph ada beberapa service utama: MON, MDS, dan MGR (selain OSD). Fungsi: Menyimpan cluster map, informasi topologi cluster: OSD, PG, pool, crushmap, quorum. Menyediakan quorum → cluster Ceph butuh mayoritas MON hidup supaya bisa ambil keputusan. Jadi semacam “otak koordinasi”: siapa OSD yang up/down, siapa MDS aktif, dll. Tanpa MON: Best Practice: Minimal 3 MON untuk quorum (HA). Dengan 3 node cluster → biasanya setiap node dipasang 1 MON. Metadata Server (MDS) Fungsi: Khusus untuk CephFS (Ceph Filesystem). Mengelola metadata file (struktur direktori, permission, nama file, inode). Membuat akses file di CephFS jadi cepat, karena OSD hanya menyimpan data mentah. Tanpa MDS: Ceph RBD (block storage) tetap jalan. CephFS tidak bisa diakses (nggak bisa mount). Best Practice: Minimal 1 active MDS + standby MDS untuk failover. Kalau banyak client CephFS, bisa jalankan beberapa MDS active (multi-MDS) biar scalable. Fungsi: Tanpa MGR: Cluster masih jalan (MON + OSD masih cukup), tapi: Tidak ada dashboard Tidak ada modul tambahan (prometheus, radosgw, balancer). Best Practice: MON → otaknya Ceph → cluster map, quorum, konsensus. MDS → khusus CephFS → urus metadata file/direktori. MGR → pengawas + dashboard → monitoring & modul integrasi.

Mobile apps are everywhere. Whether it's a banking app, a fitness tracker, or a marketplace for local goods, almost every business building digital products today has a mobile application at its core. But while app development has accelerated, security often struggles to keep up. Mobile application testing is a critical part of a secure software development lifecycle. Unfortunately, many development teams still underestimate the risks, or assume that app stores, operating systems, or third-party libraries will take care of it all. They don't. There are two sides to mobile application security testing: the application itself, and the API it talks to. Both need proper penetration testing. Most mobile apps run on iOS or Android, and a lot of teams rely heavily on the security of those platfo…  ( 8 min )

Client I am making a website for a mobile detailing business. I start with a simple roadmap when making a website for a client. First, I talk with the client about what they want. Then, I make a list of questions about their business. This is to create the content for the website, and I place it in my notes or in Google Docs. I then interview the business owner and write down the answers to all my questions. This interview allows me to form the paragraphs for the different sections and pages. I learned from The Website Architect to only begin forming the layout and design after getting the content. This allows you to make the design custom-fit to the content.

In the study of Go language, the expansion strategy of arrays and Maps is a common and classic topic. This article aims to summarize and explain the expansion strategies of arrays and Maps. In Go, dynamic arrays are called slices. A slice provides a flexible and dynamically sized array solution. When using the append function to add elements to a slice, Go decides whether to expand the capacity based on the current capacity of the slice. The strategy for slice expansion in Go is as follows: First, if the newly requested capacity is greater than twice the old capacity, the final capacity will be the newly requested capacity; Otherwise, if the length of the old slice is less than 1024, the final capacity will be twice the old capacity; Otherwise, if the length of the old slice is greater tha…  ( 9 min )

🔍Semantic HTML Importance for SEO and Accessibility*🔎 **👋Introduction ✨When I first started learning HTML, I used a lot of that looked like a header, but a search engine or screen reader would just see "a div".

A few years ago, if you didn’t speak English and had no money to buy learning resources, your options for studying technology were very limited. The quality and variety of programming material were scarce, and without someone to guide you, following the path was tough.

Choosing which technologies to learn and focus on can have a big impact on your economic future. However, if you are just starting, you can pick from the TOP 10 languages or technologies and go with the one you like the most. The dangers that can take you off track Once you start learning one technology, new opportunities, projects, or job offers …  ( 7 min )

Sidekiq is pretty much the go-to solution for enqueuing jobs for background processing when working on a Ruby-based project. It's simple to implement, has a clear DSL, and is well-supported by common testing frameworks like RSpec. That being said, and I may be nitpicking, but the standard implementation examples do add a little extra overhead if you wish to be more flexible with your job business logic, and additional test setup is required. Given we want a little background job that updates a user's name and any other business logic needed (to keep the example simple), we could create a standard Sidekiq job with that logic and call it from our code as such: class UpdateUserJob include Sidekiq::Job def perform(user_id, name) user = User.find(user_id) user.update!(name: name) …  ( 10 min )

I’ve been noticing how quickly businesses and even individuals jump on new SaaS platforms for almost everything project management, communication, analytics, you name it. They’re fast to set up, affordable at the start, and packed with features. But here’s the thing: the more I use them, the more I realize how much we have to adjust our workflow to fit the tool instead of the other way around. Sometimes I wonder if that’s slowing teams down instead of making them more productive. On the flip side, custom-built software takes longer and costs more, but it seems to give more flexibility in the long run. It grows with the business, integrates better with existing systems, and doesn’t force you into using features you don’t need. I have a Question: If you’ve worked with both SaaS platforms and custom solutions which one do you feel actually brings more value over time? Do the short-term wins of SaaS outweigh the long-term control of custom software, or is it the other way around?  ( 6 min )

Microservices and asynchronous communication are powerful tools. They let our systems scale, stay responsive, and build fantastic user experiences. We break down big, clunky applications into smaller, manageable parts that talk to each other. It sounds like a dream, right? Most of the time, it is. But there's a sneaky design flaw lurking in many async microservice architectures. It's often invisible until it's too late. This flaw isn't about crashes or error messages; it's far worse. It's silently corrupting your data, chipping away at the very trust you place in your system. We’re talking about a design choice that, when mishandled, can make your data outright wrong.

On Day 36 of your #90DaysOfDevOps journey, we’re tackling an important part of Kubernetes: Persistent Volumes (PVs) Let’s break this down and walk you through both tasks: What are Persistent Volumes (PV) in Kubernetes? Kubernetes Pods are ephemeral — which means data inside a Pod is lost when the Pod is deleted or restarted. To persist data beyond the lifecycle of a Pod, we use: Task 1: Add Persistent Volume to Your Deployment Let’s go step-by-step. Create a Persistent Volume (pv.yml) apiVersion: v1 This creates a 1Gi volume using the hostPath /mnt/data on the node (local path for testing). Create a Persistent Volume Claim (pvc.yml) apiVersion: v1 This PVC will bind to the todo-pv if the specs match. Update your deployment.yml to use the PVC Here’s the updated Deployment with volume mounting: apiVersion: apps/v1 Make sure: Apply the files kubectl apply -f pv.yml Verify Everything kubectl get pv Look for STATUS: Bound on the PVC and Running pods. Task 2: Access Data Inside the Pod Connect to the Pod kubectl get pods # get pod name Verify Data Access cd /app/data cat You should see files created or used by your app. Optional: Test Persistence kubectl delete pod 2. A new pod will be created (Deployment ensures this). 3. Check if data is still present by repeating the steps to access /app/data. You have Created and attached a Persistent Volume.  ( 6 min )

Two weeks ago, I had the pleasure and honour of delivering a keynote at the (milestone!) 20th edition of FrOSCon in Sankt Augustin, Germany.

Nail the feel and everything else (emails, backend, automation) lines up behind it. That’s why we shipped the multi-game invite selector and left the email as a polite placeholder. Pixels first; paragraphs later. When a control wants to live in more than one place (hello, Time Zone), pull i…  ( 8 min )

Problem A user needs to scale Amazon Bedrock’s Nova Pro foundation model to handle 2,100 requests per minute for high-traffic workloads. They’ve enabled cross-regional inference but hit a wall—provisioned throughput isn’t available in Frankfurt, and they’re wondering whether Ohio might solve the problem. The core pain: avoiding throttling at scale. The crux is twofold: Provisioned throughput isn’t everywhere. Not every AWS region supports it. Frankfurt (eu-central-1) is one such case. On-demand scaling has ceilings. Bedrock’s on-demand usage will throttle once you cross soft limits (requests per second/minute) unless you pre-negotiate with AWS service teams. So the real question: How do you push Bedrock Nova Pro past default throttles to reliably support thousands of requests per minute?…  ( 8 min )

I’ve been working on improving Libre, my anonymous social experiment, and just rolled out several important security and optimization changes: 1.Anonymous Authentication via Firebase – every user now has a unique anonymous session, preventing abuse while keeping the experience frictionless. 2. Sensitive Keys Removed – tokens (e.g., ipinfo) are no longer exposed on the client side. 3. Advanced Anti-Abuse Filtering – stronger detection for offensive content, spam, and injection attempts (XSS, SQLi, flooding). 4. Client + Server Validations – strict sanitization, input validation, and hardened Firebase Firestore rules. 5. No UX changes – users still just tap “Start being Libre” to join. 6. Scalability & Resilience – better protection against bots and malicious traffic. Libre stays simple for users but is now much stronger behind the scenes. Feedback is welcome. 👉 Try it here: https://libreantisocial.com  ( 6 min )

LangGraph is a framework for building stateful, reliable agent workflows. Instead of executing a single prompt-response cycle, LangGraph enables agents to operate as directed graphs, where each node represents a step, state is shared across the workflow, and execution can branch, pause, or persist. This article summarizes the core concepts, prebuilt utilities, and typical applications of LangGraph. The memory object that flows through the graph. Nodes read from and write updates to state. Managed through channels that define merge strategies: Replace → overwrite existing values. Append → add items (e.g., chat history). Merge → combine dicts/lists. Acts as the single source of truth for the agent’s execution. 🔹 Example: How State Evolves Consider a simple graph with three no…  ( 8 min )

One boring old SQL database might be the best backend in 2025. Modern web development feels like building IKEA furniture with 15 screwdrivers, none of which fit. You want to ship a simple app a dashboard, a chat tool, a personal project. Suddenly, you’re spinning up Redis for caching, Elasticsearch for search, Firebase for real-time sync, cron jobs with serverless functions, Auth0 for logins, a GraphQL server, analytics via some shady cookie tracker, and an AWS bill that could fund a coffee addiction. Here’s the plot twist: Postgres can now do most of that stuff and it’s actually good at it. Yeah, Postgres. The boring old SQL database that bootcamp tutors told you was “fine, but legacy.” It’s quietly evolved into a backend beast. With the right extensions and practices, you can replace 1…  ( 11 min )

Hello Dev community! I am a Computer Science and AI student at IE Madrid. I joined DEV to become a part of a larger community of creators where I can learn and grow, as well as record my progress over the coming years. I really enjoy coding and challenging myself as much as possible, and I continue this attitude with everything in my life including hobbies like cooking and boxing! I plan to post anywhere from casual daily insights to projects and questions for the community every week! (PS This is also my first blog, please feel free to send any tips not only on code but anything else as well!) Today's Insight My next steps are to figure out GitHub and how to create a portfolio, update my LinkedIn and CV, and spiff up on my coding skills. Hopefully I can achieve all of this during the first week of school so I can apply to the good internships ASAP before they're all gone. (Somehow, some already ended). I find it frustrating that so many companies want interns already ready to graduate, or expect ten-million and one skills to apply, but there's really nothing to do except try to learn at least a few more to maybe stand out. I know a lot of us are in the same boat with this struggle, but maybe the more we begin to enter into jobs and internships, the more change will come! I'm off to planning how to manage all of this, I hope you all are having more luck than me! :3  ( 6 min )

The automation itch every dev gets I didn’t plan to automate my life. It started with a single annoying task copying Twitter DMs into Notion. Felt dumb. Repetitive. Manual. It was the kind of thing a script should do while I eat noodles and pretend I’m productive. Fast-forward a weekend and I had an entire AI-powered workflow stack: n8n doing the orchestration, Docker keeping it sandboxed, And an AI agent layer quietly making decisions while I slept. What started as a minor itch turned into a full-blown lazy-dev automation rig. Here’s exactly how I did it, the tools I used, the screw-ups I ran into, and why every dev should automate at least one annoying task in their life. Covered in this article: What the heck is n8n and why devs should care How Docker makes automation way less painful A…  ( 10 min )

Bitnami is deprecating their Kafka images, and ZooKeeper is being removed from Apache Kafka 4.0. Time to migrate to KRaft mode with Confluent's official images for a future-proof, simpler architecture. If you're using bitnami/kafka in your Docker setup, you've probably seen this warning: ⚠️ Important Notice: Beginning August 28th, 2025, Bitnami will evolve its public catalog... All existing container images have been migrated to "Bitnami Legacy" repository where they will no longer receive updates. But there's a bigger issue: Apache Kafka is removing ZooKeeper entirely in version 4.0. Most current setups still rely on ZooKeeper, which means double trouble ahead. The Solution: KRaft Mode KRaft (Kafka Raft) eliminates ZooKeeper dependency entirely, giving you: ✅ Simpler architecture (fewer m…  ( 7 min )

What a deserialization bug, a missing trust boundary, and some ancient .NET code can teach us about secure system design. ☢️ Wait, what? In one of the most “you can’t make this up” security stories of the year, in July 2025, a vulnerability in Microsoft SharePoint, yes, SharePoint, led to unauthorized access to none other than the U.S. nuclear security agency’s internal systems. The same agency responsible for safeguarding America’s nuclear arsenal. This exploit turned into a mass-hit campaign affecting over 400 organizations globally, including notable agencies such as U.S. Department of Homeland Security (DHS) The National Institutes of Health (NIH) Fermilab (U.S. national lab) Interpol European Banking Authority Multiple Department of Energy offices worldwide (source: The Guardian) How…  ( 14 min )

Forget robots the smartest AIs are grinding skills in block-based sandboxes with full control AI agents don’t need robot arms or fancy sensors to learn sometimes, all they need is a sandbox world made of blocks and a good server. MCP (short for Minecraft Control Panel, though nobody calls it that anymore) has quietly become a go-to playground for training AI agents. It’s visual, programmable, endlessly moddable, and doesn’t fry your GPU. OpenAI even trained one of its agents to play using nothing but video frames and keyboard controls. But here’s the catch: to get serious with AI in this space, you need full control. Think automation, scripting, state resets, and full integration with your training loops. That’s where these 7 open-source MCP servers come in. They give you the power to do …  ( 9 min )

If your AI trading bot's strategy is visible on-chain, it's not intelligent, it's a sitting duck for MEV bots. The crypto world is buzzing about DeFAI, the fusion of Decentralized Finance (DeFi) and AI. Market projections suggest DeFAI could grow from $1 billion to over $10 billion by late 2025. But here's the thing most people miss: building truly smart AI agents for finance means keeping their strategies private. Otherwise, they're just expensive targets for MEV extraction. DeFAI combines DeFi protocols with AI-driven automation.

Because your future self deserves better code reviews. Let’s be real: most developers nod politely when SOLID comes up, then continue writing 500-line classes that smell worse than week-old fried eggs. Here’s the thing: SOLID isn’t about pleasing your CS professor. It’s about writing code that your future self won’t want to rage-quit from after a single bugfix. Bad code means frustration, late nights, and way too much coffee. SOLID is a language that senior devs use to communicate across years of maintenance. When you see it in a project, you don’t need to crawl line by line like some code archaeologist digging through ruins. Instead, you can predict the system’s behavior, understand responsibilities, and trust that classes aren’t hiding surprises like a clown in a sewer drain. Follow it, …  ( 12 min )

When you first dive into backend development with Node.js, it doesn’t take long before you bump into Express.js. It’s practically the default framework for building web servers and APIs in JavaScript, and for good reason, it simplifies the otherwise clunky task of handling requests, responses, and routes. In this article, we’ll take a thorough look at Express: what it is and why it exists, how to set up a simple project, how routing works in practice, and a few must-know tricks to get you comfortable. This will lay the foundation for the next article in the series (Part 2), where we’ll unlock the real magic of Express: middleware. You might be thinking: “Wait, Node.js can already create servers, why do I need Express?” That’s true, but here’s what a basic raw Node server looks …  ( 8 min )

On a quest to learn about game development with the Godot Engine, I recently took on the 20 Games Challenge.

Why I Did This to Myself Invoices are like bosses: they all look different, they all demand money, and they all ruin your day. The Tech Stack (aka Weapons of Mass Frustration) - OCR → For turning “blurred coffee-stained PDF” into “blurred text file.” - Regex → Because nothing screams fun like 200-character patterns. - ML-ish GST Predictor → Basically a model that guesses taxes better than me on exam day. - Python + pandas → To wrangle the chaos into something that looks like data. How It Works You upload an invoice. OCR panics but spits out text. Regex plays “Where’s Waldo” with GST numbers. AI pretends to be an accountant. You get structured output and tax predictions. Bugs That Almost Broke Me OCR Hallucinations: Me: “That’s ₹1200.” Regex PTSD: The BTS Incident: OCR once read “18% GST” as “BTS.” Code Snippet: My Regex Therapy Session import re def extract_gst(text): pattern = r"\d{2}[A-Z]{5}\d{4}[A-Z]{1}[1-9A-Z]{1}Z[0-9A-Z]{1}" match = re.search(pattern, text) return match.group(0) if match else "No GST found, cry harder." invoice_text = "Invoice #123 GSTIN: 22ABCDE1234F1Z5 Amount: ₹1200" print(extract_gst(invoice_text)) # Output: 22ABCDE1234F1Z5 Results (Sort of) Structured PDFs? Works like a charm. Low-quality scans? Good luck, buddy. Predicts GST fairly well — which is more than I can say about me filing taxes. What’s Next Teaching it sarcasm so it can also roast invoices. Export to Excel/CSV (for those who still trust spreadsheets). Maybe SaaS — so small businesses can suffer too. Final Thoughts This project taught me: AI isn’t about intelligence.

I had a demo ruined by backend downtime. I was demoing my Little Black Book app — a React and Express project for storing, adding, amending, deleting, sharing etc. cocktail recipes. The frontend was loading fine, but when I tried to fetch the list of drinks from the API, the request just froze. No response. No errors. Just dead air. The worst part was I knew this happens. Before the demo, I’d even prepped for it. I opened the app, clicked around, made sure the backend on Render was awake. But the demo came late in the conversation, and Render’s free tier 15-minute inactivity limit quietly kicked in while we were talking.

Searching for jobs can feel like a full-time job in itself. So I decided to do what any lazy developer would do... I automated it. 🚀 Too many platforms (LinkedIn, Indeed, remote job boards, etc.) Same repetitive filtering process every day Hard to keep track of new postings Instead of wasting my energy on job hunting, I wanted a workflow that does the boring stuff for me, only shows me relevant opportunities, and notifies me instantly. If you haven’t used it before, n8n is an open-source workflow automation tool. Here’s how my setup works: Visit the URLs of career pages or job boards, use the filters available on site and add the URL into a Google Sheet. The workflow fetches openings from those URLs, and includes/excludes jobs if the role title contains certain keywords. For each matching job, the workflow scrapes the full job description. An AI model analyzes the description and decides if the job is actually relevant. If it passes the check, I get a Telegram notification instantly. No more endless scrolling, just the jobs that actually matter to me. Saves hours of job hunting every week Never miss new opportunities Scales easily, I can add more job sources anytime Feels like I have a personal job-hunting assistant Watch the DEMO 🎥 https://youtu.be/KKYsuBKQ_No https://gist.github.com/Heapnotizer/82153323498bdf95765ce8232d0a960a 💬 Have you automated any part of your job hunt before?

Before we dive deep into today's blog, I want us to talk about what bits are. Bits are the smallest piece of information a computer understands. Bits only have 2 values; 0 or 1. Computers represent everything from symbols to text and numbers with 0's and 1's, and a combination of these 0's and 1's forms a binary number. Bitwise operators allow you to work directly with the individual bits inside the integer. Java provides; AND(&), OR(|), XOR(6^), NOT(~). When working with bits in programming, two operators you’ll often encounter are > (right shift). At first, they may look a little intimidating, but once you get the intuition, they’re actually very powerful and surprisingly easy to understand. The Left Shift Operator > The >> operator works the opposite way: it pushes all the bits in a number to the right, filling the empty spaces on the left with either zeros or the sign bit (depending on the language and whether the number is positive or negative). Example: int y = 20 >> 1; >> is like a quick way to divide numbers by powers of 2. Why Are Shifts Useful? Bit masking – Used to check or manipulate specific bits in a number. Efficiency – Shifts can multiply or divide by 2 much faster than arithmetic operations. Low-level programming – Essential in hardware control, graphics, compression, and cryptography. Quick Intuition Recap Once you see shift operators as shortcuts for multiplying and dividing by powers of two, they stop being scary and start becoming powerful tools. Whether you’re doing system programming, optimizing code, or just learning about bits, > will show up everywhere.  ( 7 min )

If you’ve ever tried to do anything across different blockchains, you know how messy it can get. Switching networks, signing multiple times, worrying about gas fees on every chain-it’s not exactly user-friendly. That’s where Biconomy’s new Supertransaction API comes in. Instead of forcing users (and developers) to juggle separate steps, it bundles everything into one smooth transaction. Think of it like clicking “one-click checkout” in e-commerce, but for Web3. What Exactly Is a Supertransaction? At its core, a Supertransaction is a single object that can include multiple instructions across different chains. You sign once, and behind the scenes all the actions happen in order-bridges, swaps, protocol interactions, whatever you need. const supertransaction = { chainId: 137, // Polygon …  ( 7 min )

Introduction The Model Context Protocol (MCP) is a powerful way to expose your systems to AI agents. But a common mistake teams make is to take an API built for humans, auto-convert it to MCP tools, and expect agents to use it effectively. APIs designed for human developers follow a very different set of rules than APIs/Tools that serve AI agents in agentic workflows. What’s intuitive for a person is often overwhelming, inefficient, and error-prone for an LLM. If we want our agents to succeed, we need to design for them from the ground up — not just repurpose what we already have. Imagine you want to enable agents to use your flight booking system by converting the current APIs you have, and you ask your agent to find the cheapest direct flight to Paris in June, This is roughly the api c…  ( 8 min )

Writing business logic in a controller or service is easy, but just because it is easy doesn’t mean it’s clean.If your models are dumb and all the brain lives in controllers, you should reconsider your approach.Imagine a scenario where an order is placed in an e-commerce system.

Place the order Calculate costing, pricing and discounts before saving Generate order number before saving Send emails to customer and store admin Produce notification sound in admin panel to get attention This is a typical example where you need to do multiple steps to complete a process. Unless you do all these steps, the operation is considered incomplete. But to achieve this, many people use a single class and cram all the logic into it to execute this whole process.

Most developers know Django for its ORM, admin, and views. But there’s a feature hiding in plain sight that often goes underused: Signals. Signals allow different parts of your Django application to communicate with each other without being directly connected. In other words, they will enable you to trigger actions automatically when specific events occur within your app. If you’ve ever worked with event listeners in JavaScript, think of signals as Django’s equivalent. At the simplest level, a signal is just a notification system. When something happens—like a user registering, a model being saved, or an object being deleted—Django can “signal” that event, and you can attach functions that respond to it. Some practical examples include: Automatically creating a profile when a user signs up…  ( 7 min )

When working with .NET Framework MVC applications, I used to use bound view models, which let me use classes on the Razor templates very easily with the autocomplete feature. This was a default feature provided for .NET Framework by Visual Studio IDE. In the Razor views, we had to define a class as a model on top, and on the other hand, in the controller, we were forced to pass the instance of that class to the view. If passed a different class instance, it would throw an error telling this view required the instance of the defined class. Once this was done, we were able to access class with a variable called Model. This gave the autocomplete feature within Razor view. I was looking for the same thing in the Laravel ecosystem, but I found none. So I practiced a pattern I call ViewModels an…  ( 8 min )

We know that there are various types of error which we might come across in coding, they are broadly classified as following types: Error in the syntax such as initializing value without declaration, absence of semicolon etc are considered syntax error. When wrong logic is applied to the code, it is called logical error. This type of error do not cause any problem in compilation or execution but they perform the wrong task, i.e. the code doesn't behave in the expected manner. These are the errors that we do not realize until the code is run, i. e. we cannot view them at compile time as they occur at runtime. These errors can usually be treated and these are then called exceptions. So exception in java is basically a resolvable event the disrupts the normal flow of program. common exceptions that we come across are: NullPointerException ArithmeticException -ArrayIndexOutOfBoundException -IllegalArgumentException -NumberFormatException So assume following code, in this I've declared an array, and its asking the user to enter an index to be retrived. As the length of array is 5 so entering index til 4 is valid and if index greater than 4 is entered in normal circumstances it would give error. But we do not want our program to crash over such pity things such as invalid input so we perform exception handling, where we make two blocks a Try block that contains the code that might cause error, by this we tell the compiler to try doing that part of code, and if it throws an error it is given to the Catch block which catches the error by its type mentioned in the parentheses and then does the action that shows us that the error has been dealt. Finally block that is executed whether any error arise or not, the only time it is not executed is when there's an error in the finally block as well, or when it contains a dead thread or when we use System.exit().  ( 6 min )

Why is your GPU cluster idle While organizations obsess over CPU and memory optimization in their Kubernetes clusters, a far more expensive problem is quietly destroying budgets: GPU underutilization. The average GPU-enabled Kubernetes cluster runs at 15-25% utilization, but unlike CPU overprovisioning, which can waste thousands of dollars per month, GPU underutilization can burn through tens or hundreds of thousands. Consider this: a single NVIDIA H100 instance costs $30-50 per hour across major cloud providers. An underutilized cluster with 20 GPUs running at 20% utilization incurs approximately $200,000 in annual compute costs alone. Yet most organizations lack the monitoring, processes, and architectural strategies to address this systematic waste. The challenge isn't just about reso…  ( 8 min )

Introduction Working with Golang is always fun and satisfying. But when it comes to scaling your application on a distributed computing infrastructure, you start to feel the real pain. To reduce such pain, numerous models and patterns were discovered. Some are cloud native (Kubernetes for example), while others need to be implemented at the architectural level. One such model is called Actor Model. We'll dive deep into what Actor Model is in this blog. An actor is an independent unit that encapsulates its own state and behavior. Actors do not share state directly; instead, they interact only through message passing. One major advantage of Actor Model is it's fault tolerant nature. Since each actor is isolated and interacts only through asynchronous messages, an anomaly or failure in one…  ( 9 min )

First gather a corpus of text. Let's call it the entire public internet. Next train a Large Language Model (LLM) against this corpus and you will get a system like Grok, Gemini or ChatGPT which approximates Artificial Intelligence (AI). Now sell this LLM to people who use it to generate content they later post to the internet. The moment you make available the first generation of your LLM, you will immediately begin developing the second generation of your LLM in order to remain competitive in the AI arms race. Gather a new corpus of text. A fresh snapshot of the entire public internet. Train your new LLM against this new corpus, knowing that it contains some non-zero percentage of LLM generated content produced by users of the first generation of your product. Now sell v2 of your LLM to more people who use it to generate more content they later post to the internet. You can see where this is going. Each new generation of your LLM is trained on a higher percentage of LLM generated inputs as the last. This leads to Macro self-training where large language models are inadvertently affecting the quality of successive generations by feeding their own outputs (and the outputs of other models) into the inputs of the newer generation of models. However inaccurate LLMs are today, we should expect them to become more deranged and hallucinatory over time. Not less. When developing the nuclear bomb, some scientists worried it might ignite the atmosphere and end the human race. This concern did not stop them from detonating the most destructive device ever constructed. If you think legitimate concerns regarding the safety of AI will be heeded, you don't understand the macroeconomics. These multi-billion dollar models are going to choke on their own excrement spraying trash across the entire internet and crash the global economy full speed into the brick wall that is The Ouroboros Problem.  ( 6 min )

Introduction In the era of 24/7 media and constant digital noise, the ability to process and act on real-time information is crucial. For any system designed to monitor, classify, and enhance media content, scalable ingestion pipelines are the backbone. This blog outlines a re-engineered real-time ingestion pipeline that successfully scaled to handle over 8 million articles per day, demonstrating a shift from traditional ETL models to AI-augmented streaming architectures.

Python’s Next Chapter A massive Python Developers Survey of over 30,000 coders shows the language keeps evolving—newer tools and modules are reshaping how we build apps. While Python remains king in data science, web dev and automation, it’s also carving deeper niches with libraries like FastAPI, Pandas and NumPy. Compared to 5–10 years ago, we’re seeing a clear shift toward type hints, static analysis and better packaging workflows, making projects easier to maintain and share. On the tooling front, PyCharm still leads the pack, but VS Code and new cloud-based IDEs are gaining ground. Packaging got a glow-up too, with more folks using Poetry and Hatch to streamline dependencies. Demographically, Python’s user base is younger and more global than ever, driving fresh innovation in AI, ML and beyond. Overall, the survey paints a picture of a maturing ecosystem that’s ready for whatever’s next. Watch on YouTube  ( 6 min )

Back to basics. Third chapter of The Rust Programming Language is about common concepts, such as variables, types, functions, and comments: we’ve already seen all of them in the previous episode, but I’ll go deeper this time. Here’s the full list of primitives you must be aware of. Rust, like any other programming language, has some reserved keywords that you can’t use to name variables, etc.; the book lists in an appendix all the keywords currently in use or that could be used in future releases. What’s interesting here is the raw identifier r# which let you use them anyway like r#keyword. I’ve already noticed it last time: variables are immutable by default in Rust, even though they are all called let. This can be confusing, coming from JavaScript, where we distinguish let from const.

Introduction AI used to be a Python-first world. Most libraries, frameworks, and tutorials lived in that ecosystem. But today, AI is no longer locked to one language. LangChain.js and LangGraph.js shows how serious the JavaScript ecosystem is becoming for building AI-powered applications. If you’re a developer trying to decide between Python vs TypeScript/JavaScript for your next AI agent project, this post will break down everything you need to know before deciding. We’ll look at LangChain and LangGraph in both languages, compare maturity, deployment, and community—and end with some practical advice. LangChain is a framework designed to simplify the process of building applications powered by large language models (LLMs). It provides tools for chaining together prompts, models, and tool…  ( 9 min )

You've mastered Compose basics. You chain modifiers like a pro: padding here, background there, maybe a click handler at the end. It feels natural, almost meditative. But, identical UIs can perform drastically differently based solely on how you order and structure your modifiers. Think of it like cooking. You can make the same dish using different techniques, one way leaves you with smooth workflow and minimal cleanup, another creates unnecessary mess and takes twice as long. Same end result, completely different efficiency. Consider this everyday chat interface element: // Looks perfectly reasonable, right? Box( modifier = Modifier.padding(16.dp) // First modifier ) { Column( modifier = Modifier.padding(16.dp) //redundant! ) { Text( "Breaking News"…  ( 7 min )

The Problem Last month, our team started getting complaints that our Next.js application felt sluggish. Users were experiencing slower navigation between pages, even though we hadn't made any major changes recently. The app was noticeably slower in production environments. So I started investigating this performance regression and what I discovered was a subtle but impactful issue with how Next.js handles prefetching for dynamic routes. Our application uses Next.js 15 with App Router, and we were using the standard Link component which handles prefetching automatically. Initially, this seemed fine—prefetching should make navigation faster, not slower. So why were we seeing the opposite? The breakthrough came when I examined our recent routing changes. We had recently implemented internat…  ( 9 min )

I’ve worked on SaaS products where the Settings page quietly swallowed the whole experience. Not in one dramatic release – in gentle increments. A toggle here to “keep options open”, a checkbox there to “unblock a stakeholder”, a dropdown to “cover an edge case”. It feels generous in the moment. It reads like hesitation later. This is a personal take on the wall-of-settings problem - a little softer round the edges, more liberal in spirit, and firmly on the side of users who want to get on with their day. Confession: I’ve helped build those walls. This is how I try to undo them now. Bloat rarely looks like clutter while you’re adding it. It looks like kindness.

Beyond Code: Why UX/UI Design is Essential for Every Developer Think about it: you can build the most performant, bug-free, and elegantly architected backend system, but if the user interface is confusing, clunky, or frustrating, your users will simply abandon it. Their experience dictates the success of your project, regardless of the brilliance under the hood. It’s time for developers to step out from behind the command line and embrace the human element of their creations. The Developer's Shifting Role: More Than Just Code Embracing UX/UI principles allows developers to be more proactive. Instead of just implementing designs, they can contribute valuable insights during the design phase, flagging potential technical challenges or suggesting more user-friendly alternatives from an implementation perspective. This foresight can save countless hours of rework and prevent costly mistakes down the line. Bridging the Gap: What Exactly is UX/UI? FULL-Post bit.ly/4lTqHDA  ( 6 min )

Recently Meta announced that they will allow the use of AI tools in interviews. This changes the way candidates prepare for these interview. After having solved 700+ Leetcode problems I realized that after a certain point, the learning saturates. There is also very little you can learn from grinding coding websites that can be translated to real-world SDE tasks. Sure, knowing how to work with heaps is a good skill to know when you want to implement small in-memory priority queue or knowing topological sorting in case you are trying to make a package manager.

“A portfolio isn’t just a website. It’s your story, your brand, your invitation to connect.” – Every web developer ever (including me) Back in early 2022, my developer journey started with a humble, single-page website: a few lines of HTML, home-baked CSS, and a hint of JavaScript. I hosted it on GitHub Pages at RD's Portfolio. It did the job: showcasing projects, sharing my bio, and providing a contact method. But as my skills (and ambitions) grew, the limitations of this static site became glaringly obvious. Fast forward to 2025. I rebuilt my personal site from the ground up as a 3D, interactive experience Aetheria. This wasn’t just a “glow up” for my developer identity.

Just deploy everything to us-east-1, toss it behind an API Gateway, slap a global CDN on top, and call it scalable. That’s what all the blog posts said, right? “Don’t worry about infra. Just use the cloud.” But somewhere between the $400 surprise bill, the cold starts, the 500ms latency to users in Singapore, and my fifth “is this region down?” panic spiral… I started to wonder: Is this what modern infrastructure is supposed to feel like?

Most founders rush into building an MVP. But here’s the truth: an MVP isn’t just a product, it’s a test of your hypothesis. Skip a few critical steps, and you risk wasting time, budget, and trust. Here’s what to do before you write a single line of code. 1) Define the Problem, Not the Product Your job isn’t to build features, it’s to validate a problem worth solving. 1. Create mockups, landing pages, or even run “manual MVPs.” 2. Collect signals that people want the solution before you ship it. 2) Minimum Lovable Product > Minimum Viable Product “Viable” is too cold. Your MVP should be usable and memorable. Delight creates stickiness. 3) Flip the Process: Demo → Sell → Build Instead of Build → Demo → Sell, try this: Sketch solutions (Lean Canvas, mockups) Validate with demos, pre-orders, or feedback Build what people already proved they want This cuts down on risk and prevents feature bloat. 4) Be Lean. Be Metrics-Driven. Track early signals: Who’s clicking? Who’s signing up? What’s converting? If something doesn’t move the needle, cut it quickly. Your MVP’s job is to collect learning, not to ship a perfect product. TL;DR An MVP isn’t about speed alone. It’s about validating with empathy. Build something small, lovable, and data-driven — and you’ll have the right foundation to scale.  ( 6 min )

Web development is more than just making things “look good.” Under the hood, the way you structure your HTML has a huge impact on how search engines and assistive technologies (like screen readers) interpret your content. This tutorial covers: ✅ What Semantic HTML is ✅ How to use it properly ✅ Why it improves SEO ✅ Why it improves accessibility ✅ Examples with code Semantic HTML refers to using HTML tags that carry meaning about the type of content they contain. Examples: → Introduces a page or section header → The primary content of the page → Independent, self-contained content (like a blog post) → Navigation links → Footer information Non-semantic tags (like and ) tell nothing about the content. They are useful for styling/layout but don’t provide meaning. Think of semantic HTML as “HTML that explains itself.” Helps Google and other search engines understand your content. Improves rankings because crawlers know which parts are important. Increases chances of getting rich snippets in search results. ♿ Accessibility Screen readers rely on semantic HTML to announce content properly. Example: A element signals “navigation menu,” making it easier for users to jump around the page. Keyboard navigation becomes smoother. html My Blog Home | Articles | Contact First Post This is my first article about web development. © 2025 My Blog  ( 6 min )

Most text counters work perfectly for Latin-based languages, but Japanese presents unique challenges: Multiple Writing Systems Japanese uses three different scripts simultaneously: Hiragana (ひらがな) - phonetic characters Katakana (カタカナ) - typically for foreign words Kanji (漢字) - logographic characters borrowed from Chinese A single sentence like "私はプログラマーです" contains all three systems, and each has different counting implications.

In other words, it’s the “volatility of volatility.” By knowing the VVIX current value, traders can get an idea of how unpredictable the market might be and adjust their strategies accordingly. What is VVIX? The VVIX is a volatility index created by the Chicago Board Options Exchange (CBOE). While the VIX shows how volatile the S&P 500 is expected to be, the VVIX shows how volatile the VIX itself is expected to be. High VVIX values → Expect bigger swings in the VIX and more market uncertainty. Low VVIX values → Market…  ( 7 min )

Lucius headed up to Smuggler Mountain’s old mine near the Aspen Ideas Festival and kicked things off with the echo-friendly “Dusty Trails” deep in the Cavern. They then moved outside for a sunlit set overlooking the Roaring Fork Valley, spinning through “Final Days,” the sugary “Gold Rush” (where Jess Wolfe and Holly Laessig’s harmonies really shine) and wrapping up with the heartfelt ballad “Mad Love” (complete with a few grasshoppers chiming in). Behind the scenes, a tight-knit crew led by director Mito Habe-Evans, editor Nickolai Hammar and audio engineer Neil Tevault helped pull off the rustic meets indie-pop gig, with shout-outs to everyone from Smuggler Consolidated Mines to local friends who made the whole field recording dream a reality.

If you’ve ever pieced together a backend with Express routes, cron jobs, background workers, and a few AI agents duct taped together, you’ll know it works… but it’s not exactly pretty. You end up with code scattered across files and folders, logs in three different places, and brittle workflows that are hard to debug or extend. Recently, I came across Motia, and it kind of blew my mind. It’s an open source backend framework that actually feels modern, and dare I say, fun to use. Motia is a code first framework that helps you build APIs, background jobs, scheduled tasks, and AI agents, all in a single project, with a shared runtime and clean visual feedback.

Introduction Artificial Intelligence (AI) is changing how software gets built. From auto-completing lines of code to generating entire functions, tools like GitHub Copilot and ChatGPT are redefining productivity in programming. They promise speed, efficiency, and fewer errors. But behind the hype lies an uncomfortable question: Will AI eventually replace developers altogether? There is nothing wrong with using better tools. Ignoring them just makes your work harder for no reason. Developers have always embraced innovations such as compilers, frameworks, and cloud services that made coding more efficient. AI is simply the next step in that evolution. The real danger is not that AI will replace developers, but that developers might replace their own thinking with AI. Writing code isn’t jus…  ( 8 min )

When building or integrating APIs, you’ll often come across two terms that sound similar: callbacks and webhooks. Both involve one system sending data back to another, but they serve different purposes. Let’s break them down. A callback is a URL you provide to an API when making a request. The API uses that URL to send back the result of that specific request. Triggered by: A request you initiated. Used for: Asynchronous responses. Scope: Only for the request that included the callback URL. 👉 Example: https://yourapp.com/ft-callback). Once the bank finishes processing, it POSTs the result (success or failure) to that callback. { "transactionStatus": "SUCCESS", "amount": 100, "transactionReference": "CSS472TCP" } ✅ Purpose: Tie back the outcome of a request you made earlier. A webho…  ( 7 min )

Set the exact date, time, and time zone for your content to go live - no manual…  ( 8 min )

Pattern: Two Pointers & Fast-Slow Pointers 🔹 Why This Pattern? Two Pointers (and its fast-slow variant) is one of the most frequently tested patterns across FAANG interviews. It appears in: Arrays → sorted arrays, pair-sums, container problems. Strings → palindrome checks, valid substring problems. Linked Lists → cycle detection, middle node, removing N-th node. Intervals → merging, intersecting timelines. It is optimal in problems where brute force = O(n²), but two pointers optimize to O(n). Best for sorted arrays and string palindrome checks. Find two numbers in a sorted array that sum up to target. class Solution { public int[] twoSum(int[] numbers, int target) { int left = 0, right = numbers.length - 1; while (left < right) { int sum = n…  ( 7 min )

Sliding Window Mastery (Fixed + Variable) 🔹 Why Sliding Window? Sliding window is one of the most universal FAANG patterns. Google: loves optimizing substrings & arrays with O(n). Amazon: standard repetition of substring/array window. Meta (Facebook): focuses on variable windows with conditions. Apple: adds edge constraints (like k-size + max/min). Netflix: applies it in streaming/log analysis contexts. Used when window length is known (like k). int slidingWindowFixed(int[] arr, int k) { int left = 0, sum = 0, maxSum = 0; for (int right = 0; right k) { sum -= arr[left]; left++; } maxSum = Math.max(maxSum, sum); } return maxSum; } Used…  ( 6 min )

Before Oracle Database 23ai, the awrsqrpt.sql script was commonly used to analyze the evolution of a SQL statement’s execution plan, plan statistics, CPU usage, I/O, and elapsed time over a specified period. However, this approach had two main limitations: It required specifying two specific AWR snapshots. The information provided in its report was relatively limited. Sample Output of awrsqrpt.sql: The REPORT_SQL function provides a graphical report in HTML format, allowing for the analysis of: Execution plan history Cursor sharing information Optimizer statistics history Index details And more REPORT_SQL Function: SQL> desc DBMS_SQLDIAG.report_sql Parameter Type Mode Default? --------- -------- ---- -------- (RESULT) CLOB SQL_ID VARCHAR2 IN DIRE…  ( 7 min )

The goal of IT asset discovery is to create a comprehensive, real-time view of all IT assets. In simple terms, it’s about knowing what devices and software your busi…  ( 17 min )

Greedy algorithms are all about making locally optimal choices at each step, hoping to reach a globally optimal solution. Amazon frequently uses this pattern in scheduling, interval, and resource allocation problems. Use Greedy when: A problem involves optimization (maximize/minimize something). The problem can be solved by sorting + local decision-making. Once a choice is made, it doesn’t need to be reconsidered (no backtracking). 👉 Amazon-style phrasing: n activities with start and end times. Select the maximum number of non-overlapping activities. import java.util.*; public class ActivitySelection { static class Interval { int start, end; Interval(int s, int e) { start = s; end = e; } } public static int maxActivities(List activities) { a…  ( 7 min )

Amazon loves Trie-based problems because: They simulate autocomplete search, spell-checkers, URL routing, and dictionary lookups. Tries are highly efficient for prefix-based queries. 👉 Amazon-style phrasing: insert, search, and startsWith. class TrieNode { TrieNode[] children = new TrieNode[26]; boolean isEndOfWord; } public class Trie { private TrieNode root; public Trie() { root = new TrieNode(); } // Insert word public void insert(String word) { TrieNode node = root; for (char c : word.toCharArray()) { int idx = c - 'a'; if (node.children[idx] == null) node.children[idx] = new TrieNode(); node = node.children[idx]; } node.isEndOfWord = true; } // Search word public bo…  ( 8 min )

Amazon interviewers love matrix/grid problems because they test: Traversal strategies (row-wise, column-wise, diagonals, spiral). Boundary handling. In-place transformations. BFS/DFS usage for pathfinding. These problems simulate warehouse navigation, routing, and optimization problems that Amazon faces in real-world systems. 👉 Amazon-style phrasing: n x n matrix, rotate it by 90 degrees clockwise in-place. public class RotateImage { public static void rotate(int[][] matrix) { int n = matrix.length; // Step 1: Transpose for (int i = 0; i < n; i++) { for (int j = i; j < n; j++) { int temp = matrix[i][j]; matrix[i][j] = matrix[j][i]; matrix[j][i] = temp; } } // Step 2: Reverse…  ( 8 min )

Amazon loves to test whether you can use bits for optimization instead of relying on brute force or extra memory. space-efficient, fast solutions to problems involving: Unique numbers Parity checks Power-of-two checks Subset generation Bit manipulation means solving problems using binary representation and operators like: & (AND) | (OR) ^ (XOR) ~ (NOT) > (right shift) 👉 Why Amazon asks this: Very efficient (O(1) per operation). Saves memory (no extra DS needed). Trains you to think at a low level. 👉 Amazon-style phrasing: public class SingleNumber { public static int singleNumber(int[] nums) { int result = 0; for (int n : nums) { result ^= n; // XOR cancels out duplicates } return result; } public static void main(…  ( 7 min )

Amazon loves ranking, recommendation, and selection problems—whether it’s finding the top-selling products, most visited pages, or most frequent queries. These problems usually need priority queues (heaps) or bucket sorting. This is where the Top-K Elements Pattern shines. The idea is to efficiently find the K largest/smallest/frequent elements without sorting the entire dataset. Sorting takes O(n log n). With a min-heap of size K, we can reduce this to O(n log k). In some frequency problems, bucket sort can achieve O(n). When Amazon uses this pattern: Product ranking (top K sellers). Log analytics (most frequent IPs or queries). Performance optimization (K nearest servers, K largest numbers). 👉 Amazon-style phrasing: nums and an integer k, return the k most frequent elements. import java…  ( 8 min )

If you’ve ever used a tool like Slack, Trello, or even Google Docs, you’ve already experienced SaaS in action. It is hard to imagine modern work without it. According to a recent report by BetterCloud, nearly every company, almost 99%, now depends on at least one SaaS product to get things done. But what we don’t often see is the structure underneath, the software architecture that holds everything in place. And truthfully, this part can make or break a product. It is not just about writing clean code or choosing the latest tech stack. It is about building something that can grow, adapt, and survive, even under pressure. The choices made early on about architecture will affect everything from how quickly you can release new features to whether your app crashes when the number of users incr…  ( 13 min )

👉 When Amazon asks for problems involving running medians, balancing data, or minimizing differences, Two Heaps Pattern is the go-to approach. Maintain two heaps: Max-Heap → stores the smaller half of numbers. Min-Heap → stores the larger half of numbers. Balancing ensures: Max-Heap size ≥ Min-Heap size Difference in size ≤ 1 ⚡ This allows quick median or balancing decisions in O(log n). 👉 Amazon-style phrasing: import java.util.*; public class MedianFinder { private PriorityQueue maxHeap; // lower half private PriorityQueue minHeap; // higher half public MedianFinder() { maxHeap = new PriorityQueue(Collections.reverseOrder()); minHeap = new PriorityQueue(); } public void addNum(int num) { if (maxHeap.isEmpty() || num…  ( 8 min )

Managing Branches and Merging in Git In this exercise, I worked on the official project repository located at /opt/official.git. The objective was to create a new branch, add a file, merge changes back into the master branch, and push everything to the remote repository. This task ensured proper branching workflows, safe integration of new changes, and clean synchronization with the remote repository. Below are the detailed steps I followed to complete the exercise. Note: I used sudo for this exercise since the respective directories were owned by root rather than the user natasha on the storage server. Alternatively, chown could be used to change ownership. The project repository had already been cloned under /usr/src/kodekloudrepos/official. I moved into this directory to begin the work: cd /usr/src/kodekloudrepos/official Before creating a new branch, I switched to the master branch and updated it with the latest changes from origin: sudo git checkout master sudo git pull origin master A new branch named xfusion was created from master: sudo git checkout -b xfusion The provided index.html file, located at /tmp/index.html, was copied into the repository root directory: sudo cp /tmp/index.html . The file was staged and committed into the new branch: sudo git add index.html sudo git commit -m "Add index.html file" The xfusion branch was pushed to the remote repository to keep origin updated: sudo git push origin xfusion I switched back to master and merged the changes from xfusion: sudo git checkout master sudo git merge xfusion Finally, the updated master branch was pushed back to the origin: sudo git push origin master The index.html file is now part of the repository in both the xfusion branch and the master branch. Both branches were successfully pushed to the remote origin. The task validated Git best practices: creating feature branches, committing changes safely, and merging them back into the main branch.  ( 7 min )

💡 Every AI headline sounds the same: "This new model has 70B parameters" or "Trained on 2 trillion tokens". Sounds impressive, right? But what does that actually mean for your business - and more importantly, your budget? Let’s break it down with a practical lens. 🚀 Meet ShopEase: A Startup at a Crossroads On a small AI model, it worked fine for FAQs. Not so fast. 🧩 What Parameters Really Mean (Without the Jargon) GPT-2 → 1.5B parameters. 175B parameters. 1.76 to 1.8 trillion parameters. Training GPT-3 reportedly cost $4.6M in compute. That’s before you even use it. So when you hear "70B parameters", don’t think "smarter". Think "heavier to run, more expensive to maintain". 💵 Tokens: The Meter That Never Stops Running you still pay per token when you use it. GPT-4o-mini: ~$0.15 per 1M tokens. 👉 That’s a 200x difference in cost. Back to ShopEase: Their chatbot handles 1M queries/month. On GPT-4o-mini → $150/month. Same queries. Same customers. But $29,850 of “AI tax” each month. 📉 The Hidden Trap of Scaling Blindly Scaling without strategy can: Burn budgets (AI bills growing faster than revenue). Add latency (customers waiting 5+ seconds per answer). Hurt ROI (extra cost may not mean happier customers). ShopEase realized: instead of jumping to a mega-model, they could fine-tune a medium model with their support transcripts for far cheaper — and better aligned to their domain. ✅ Key Takeaway Parameters = capacity (how much the AI can "know"). Tokens = cost (every interaction charges you). Bigger ≠ automatically better. If you don’t understand these two levers, your AI project isn’t a strategy - it’s a gamble. 👉 Coming next in this series: "Small vs Medium vs Large Models: The Trade-Offs That Matter."

What’s worse than a date parser throwing an error? One that doesn’t—and gives you the wrong answer. 💀 Imagine this: "12/01/2024" → interpreted as January 12th, when the user meant December 1st. No warnings. No logs. Just bad data flowing through your systems. This is why we added confidence scoring to our Date Normalizer API. It’s not a gimmick—it’s a foundational feature that turns parsing from a black box into a transparent, predictable process. Date strings are messy.

How seasons of year affect programming productivity in different countries We've reverse-engineered five years of GitHub activity (2020-2024) to uncover the hidden seasonal trends that dictate how and when programmers ship code. Find out how the seasons affect your peers worldwide: Devs slow down in Q3 across the region. They hit the brakes in July and August, with activity dropping 8.5% compared to the Q4 hustle. Programmers take a break for summer and major holidays, making their code output 24% lower than in winter. Programmers from these regions start slow and build momentum throughout the year, with their peak activity increasing by 21% at the end of the year. And then there's China with an opposite trend. Chinese developers slow down in Q4 by 17%, completely flipping the script on the global trend. The top of this list takes Peru. Our data shows a 34.6% difference between their least and most active coding seasons. And there are countries where code output is consistent no matter what. Israel takes the top spot in this rating, with just a 4.4% range in its work patterns throughout the year. Check out the interactive report to find your country, discover a new trend or a surprising outlier. Explore your country Notes The statistics are based on public activity only. Open-source productivity may not be the same as overall productivity. For our ratings, we analyzed only countries with over 100,000 contributors in the five-year dataset. On a personal note, this report was a fun project I completed in my first week of learning the Tableau tool. Any feedback is appreciated.

When your website or app is behind Cloudflare, all incoming requests appear to come from Cloudflare’s IP addresses rather than your visitors’ original IPs. To ensure your SafeLine WAF doesn’t mistakenly block legitimate traffic, you should whitelist Cloudflare’s official IP ranges. Avoid false positives: Ensures your WAF doesn’t block Cloudflare’s reverse proxy servers. Improved performance: Reduces unnecessary filtering on trusted network traffic. Essential for CDN and security services: Many Cloudflare features (e.g., DDoS mitigation, caching, WAF) require your backend to trust their IPs. Rule library snapshot: Whitelist rules: 1 Blacklist rules: 0 SafeLine version supported: 7.3.0 and above Rule details: Type: Whitelist Condition: Allow requests from all IP ranges published by Cloudflare Cloudflare regularly updates its IP ranges, so it’s best practice to check their official list and update your SafeLine configuration accordingly. Official source: https://www.cloudflare.com/ips/ Go to the SafeLine WAF management console. Create a new allow rule. Add Cloudflare’s IP ranges (both IPv4 and IPv6) as conditions. Save and deploy the rule. Periodically review Cloudflare’s IP list for updates. If you continue to experience issues, feel free to contact SafeLine support for further assistance.

Every few months, a new productivity app launches with the same promise: I’ve fallen for that pitch more times than I’d like to admit. Notion, ClickUp, Coda, Airtable — you name it, I’ve tried it. And while some of these tools are powerful, none of them truly replaced everything. Here’s what I learned the hard way: the “all-in-one” dream almost always fails. And the reason isn’t the tools themselves — it’s the way humans actually work. The Problem With “All-in-One” Tools Feature bloat → Instead of doing one thing exceptionally well, all-in-one tools do five things “okay.” Notion, Trello, ClickUp… and the Same Cycle Or ClickUp: it does tasks, docs, goals, dashboards… but the more you add, the slower and more overwhelming it becomes. Or Trello: great for visual project boards, but once you start needing docs, AI help, or team comms, it starts to feel like just one piece of the puzzle again. Each of these tools works. But none of them work for everything. What Actually Works: The Hybrid Stack For me, that looks like: Notion → Knowledge base + long-term planning. Google Calendar → Hard deadlines + time blocking. Slack/Discord → Team comms. FlowTask → Quick execution. One prompt → structured workspace with tasks, deadlines, and docs, plus a context-aware AI assistant (FlowBot) that helps inside the work itself. Instead of forcing everything into one mega-tool, I use the right tool for the right job. Why Flow Over Features Wins The best tool is the one that gets you from idea → execution with the least friction. “All-in-one” sounds good on paper, but in real life, flexibility and speed matter more. Final Thoughts For me, it’s no longer about cramming everything into one app. It’s about picking a small stack that works together — and staying focused on the actual work.  ( 7 min )

You're building your WordPress site and need icons. Simple enough, right? Then you realize your theme has maybe three decent icons, and they don't match your design at all.

Docker is a well known containerization tool, which most of us have either used it or have heard of it. Even though docker is used by many and is widely known about, there seems to be a lot of misconceptions floating around regarding it. Please note that this is not a docker tutorial, but a dive into what docker is and how it works under the hood. Before learning more about docker itself, let's first learn what a container is. A container is an isolated environment that contains the application code, required packages, tools, configuration and other requirements so that the packaged software can be run anywhere and can be perfectly recreated. So what's wrong with traditional methods? Due to difference in environments like operating system (Windows, Linux, MacOS, etc.), binary versions, de…  ( 12 min )

When it comes to productivity, we’ve reached a paradox: we’re overloaded with productivity tools. Notion, Trello, ClickUp, Todoist, Asana — they’re all excellent, yet sometimes, using them feels like another task on my to-do list. I’ve often caught myself setting up pages, creating templates, color-coding tags… instead of actually working. It made me realize: productivity tools should reduce friction, not create new layers of it. The Hidden Cost of Over-Customization This is where I think the next wave of productivity lies: zero-setup workflows. From Idea → Workspace, Instantly FlowTask) that takes a different approach: you type one prompt, like “Launch a podcast”, and it generates a ready-to-use workspace — with tasks, deadlines, notes, even content prompts. It feels less like “setting up a system” and more like jumping straight into execution. Instead of thinking “How should I organize this?” you immediately start doing it. Context is King: Enter AI That Knows Your Work That’s why I added a feature (FlowBot) that lives inside the workspace itself. It reads the page you’re on and responds based on that content only. Example: I dumped a contract draft into a workspace and asked it, “Flag risky clauses.” It highlighted three and explained why. That’s not just convenience — that’s context. Why This Matters for Productivity Enthusiasts Less setup → more execution. AI embedded into flow → no more app-hopping. Tailored workspaces → aligned with specific goals, not generic templates. I don’t think FlowTask (or any single tool) will “replace Notion.” 👉 My takeaway: the future of productivity tools isn’t “more features.” It’s less friction.  ( 6 min )

The Psychology of Prompts: Why Wording Changes Everything Jaideep Parashar ・ Aug 28 #ai #beginners #productivity #webdev  ( 6 min )

Introduction When you deploy an ec2 instance or any server instance, it defaults to SSH in port 22. You already know it, so do the whole world and all of the hackers. So, most of the automated attacks start by scanning the known ports, say 22 for SSH. One of the many ways to mitigate that is to change the port to a different port. Yes it won't make it bulletproof, but it will surely reduce the chances of brute force attacks. This method is applicable for all kinds of servers, including your Virtual Machines, but since I have an aws cloud account, I will use that, you can just use GCP Compute instance, Azure VM as well. In simple words, it means hiding something from the attackers, believing if the attackers can't see they can't exploit. Kind of removing your door to an unexpected loca…  ( 7 min )

If you ask “Explain the weather like I’m a kid planning a picnic”, you’ll get playful, simple advice. Same tool. Same question. Different psychology of framing. 3 Principles of Prompt Psychology 1️⃣ Specificity = Quality The more specific you are, the less the AI has to guess. “Write a story.” “Write a 200-word story about a kid discovering a robot in his backyard. Make it adventurous, not scary.” 2️⃣ Role Assignment = Perspective The role you assign changes how AI “thin…  ( 8 min )

🎬 "Ever wondered why your app’s data disappears when you stop a container? In this episode, we uncover Docker Volumes — your key to persistent, reliable, and sharable data storage." By default, Docker containers are ephemeral — which means: When the container stops, its filesystem is wiped. All your app logs, databases, and uploads? Gone. 🫠 This is great for clean environments… but not if you need data to stick around. Enter: Docker Volumes. A volume is a special folder outside the container, managed by Docker. Think of it like: A USB drive you plug into your container When the container is deleted, the USB (volume) stays intact You can re-attach it, share it across containers, and even back it up. docker run -d \ --name mysql \ -e MYSQL_ROOT_PASSWORD=mysecret \ -v mysql-data:/var/lib/mysql \ mysql:latest ✅ This creates a volume mysql-data that stores the DB. docker volume ls docker volume inspect mysql-data docker volume rm mysql-data docker volume prune Type Use Case Named Volume Long-term data (MySQL, logs, uploads) Bind Mount Dev mode (sync local folders) docker run -d \ -v $(pwd):/app \ -w /app \ node:18 \ npm start ✅ Any change you make locally reflects inside the container in real-time. Use named volumes in production Use bind mounts for live development Clean up unused volumes regularly In Episode 7, we’ll explore: How containers talk to each other Networks, bridges, ports, and real examples (Node + DB) Did you try volumes in your app yet? Still confused between named volumes and mounts? Drop a question — I’d love to help you debug or design the best volume setup. ❤️ If this episode helped keep your data safe, give it a like or share it with someone building with Docker. 🎬 Next: “Docker Networking — How Containers Talk Behind the Scenes”  ( 7 min )

Introduction: The Business Challenge Airlines frequently face last-minute seat availability changes due to cancellations or no-shows—especially in premium cabins. These situations pose both a revenue opportunity and a customer experience challenge. Automating the seat reassignment process with a coordinated multi-agent AI system can unlock real-time upselling potential and smoother operations while respecting regulations like ADA compliance. Complex workflows—such as seat monitoring, passenger matching, messaging, staff alerts, and decision tracking—are better handled by specialized AI agents rather than a monolithic model. A multi-agent approach enables each component to focus on a defined role, mirroring how human operational teams effectively manage complex tasks. KaibanJS is an open-…  ( 8 min )

“I quote others only in order the better to express myself.” *Context & Reflection Michel de Montaigne, the French Renaissance thinker credited with inventing the personal essay, penned this powerful line in his work "Of the Education of Children." It's a reminder that quoting isn't mimicry — it’s a method of understanding, refining, and voicing our own ideas more clearly. In tech and writing—especially when crafting tutorials, documentation, or personal blogs—we often lean on external sources. But Montaigne’s insight is timeless: we quote not to borrow authority, but to clarify what we ourselves are trying to say. Cite as Context, Not Crutch: When quoting, use the source to support or illuminate your perspective—not to replace it. Frame with Your Voice: Introduce and comment on quotes. Don't let them speak for you—let them speak with you. Use Sparingly to Strengthen: One powerful quote in the right place can elevate your point more than several filler references. Add Reflective Commentary: Ask yourself, “Why does this quote resonate with me?” Then share that thought. We all stand on the shoulders of those before us. But it’s our own vision that matters most. Montaigne reminds us that quoting is a creative act—when it helps express something only you can say.  ( 6 min )

A common thought many developers have: “If there’s a free alternative, why would I ever pay?” Especially in software engineering, we rely heavily on open-source. Many of us joke: If I can use it for free, good luck trying to make me pay. But as I’ve gained more years of experience, I realized that some high-quality paid tools save me so much time and mental energy. If open-source tools are the “bricks and mortar,” then these paid tools are more like ready-to-use prefabricated modules — they let me focus on what actually matters: writing business logic, designing systems, and delivering value. Here are the five paid subscriptions I happily continue using in 2025. By now, most developers are used to AI coding tools. From GitHub Copilot to various IDE extensions, the market feels crowded.

Cut development time by 40-60% with native AI tools and workflow automation that transform routine tasks into intelligent, self-managing processes The integration of AI with Webflow is fundamentally changing how developers and designers approach web development in 2025. This article explores how agencies can leverage AI automation to deliver faster turnarounds while maintaining quality, transforming traditional development workflows into intelligent, self-managing systems. Webflow's native AI Assistant now generates new page sections using existing design systems, while third-party tools like Miyagi bring unprecedented automation capabilities. Miyagi's specialized agents—Design, Code, and CMS—work directly within projects to clean styles, fix accessibility issues, write JavaScript/CSS, and automate content operations. Users report saving hours on tasks that previously took days. The ecosystem extends beyond Miyagi. Tools like n8n enable complex workflow automation connecting Webflow with AI models from OpenAI to Anthropic's Claude. Asset Bae automates image optimization and alt text generation, while Jasper handles on-brand content creation at scale. For marketing teams, the practical applications are immediately valuable: automated CMS updates, SEO optimization, workflow automation connecting CRMs and analytics platforms, and AI-powered localization for global reach. The article provides crucial ROI insights—67% of business leaders expect AI to reshape their organizations within two years, yet only 31% can evaluate ROI within six months. Interestingly, productivity has overtaken profitability as the primary ROI metric in 2025. The guide recommends tracking development time reduction (target: 40-60% for routine tasks), content generation speed, and project turnaround times. Implementation advice emphasizes starting small, choosing native solutions, and scaling gradually. Discover the complete AI automation guide for Webflow →  ( 6 min )

Background: Why Look for an Alternative? As indie developers or designers, we often need to make quick edits to images — change a background, blur out distractions, recolor, or adjust a character’s look. Traditional tools like Photoshop or Figma plugins have two big problems: High learning curve: You need to understand layers, masks, and a ton of features just to do a small change. Low efficiency: Even minor edits can take dozens of clicks. That’s why I started experimenting with AI tools. After trying several, I landed on Nano Banana Image Editor 👉 https://www.nano-banana-ai.net/.

Recently I saw an interesting combination usage of Mutex and suspendCancellableCoroutine. This combination produces queue-like behaviour where it processes one-at-a-time in FIFO order even though there is no pop() / peek() or explicit queue data structure. If you have used Snackbar in Jetpack Compose, you have experienced this combination already (link). SnackbarHostState.showSnackbar() is suspending and ensures only one snackbar is shown at a time. suspend fun showSnackbar( message: String, actionLabel: String? = null, duration: SnackbarDuration = SnackbarDuration.Short, ): SnackbarResult = mutex.withLock { try { return suspendCancellableCoroutine { continuation -> currentSnackbarData = SnackbarDataImpl(message, actionLabel, duration, continuation) } } finally { currentSnackbarData = null } } Mutex.withLock { ... } ensures only one caller enters the block at a time; other callers suspend and will continue in FIFO order. suspendCancellableCoroutine { continuation -> ... }: suspends the caller and hands you a Continuation. Later, when the snackbar is dismissed or its action is pressed, the implementation calls continuation.resume(result) to wake the suspended caller with a SnackbarResult. If the job is cancelled meanwhile, the continuation is cancelled promptly. Combining these, we have a queue behaviour allowing single operation (in this case snackbar) to be shown on the screen. This pairing feels like a queue because the first call must complete before the next call proceeds. However, it’s important this is not same as java.util.Queue we have seen on Java.

Consistent Hashing in Java — Step-by-Step Example In my previous explanation of Consistent Hashing, we walked through an example with servers S1–S4 and keys K1–K6 distributed on a hash ring. Now let’s take the same example and implement it in Java, so you can see how it works in practice. Consistent Hashing solves the rebalancing problem when servers are added or removed. Servers and keys are placed on a ring using a hash function. A key is assigned to the first server clockwise from its position. When a server is removed, only a subset of keys move (not all). When a new server is added, it takes over part of the key space from its neighbor. We’ll implement this using a TreeMap: Keys: hash positions (0–100 range for simplicity) Values: server identifiers (S1, S2, etc.) O…  ( 7 min )

The Meeting Room Divide Picture this: you’re in a leadership meeting. The Head of Sales is energized, pacing at the front of the room: “There’s a huge opportunity in this new vertical. If we move fast, we could add 20% revenue this quarter!” On the other side of the table, the Head of Engineering calmly counters: “We need to improve our deployment process. Change failure rates are too high, and our lead time is slowing down.” Both are speaking passionately, both are right — yet they sound like they’re on different planets.

Unlock the Power of Pre-trained Models: An Introduction to Transfer Learning in Deep Learning Imagine training a dog. You wouldn't start by teaching it calculus before basic commands, right? Similarly, in deep learning, training a model from scratch on massive datasets can be incredibly time-consuming and resource-intensive. This is where transfer learning comes in – a powerful technique that lets us leverage the knowledge gained from solving one problem to tackle another, related one. Essentially, it's about taking a pre-trained model, fine-tuning it, and applying it to a new task, dramatically speeding up the learning process and often improving performance. Transfer learning is a machine learning method where a model developed for a task is reused as a starting point for a model on a …  ( 10 min )

Hello, dev community! Zuni Baba here. Some of you might know me from my work with the Power Platform and my PL-400 certification.

That means conquering the AZ-204 (Azure Developer) and AZ-400 (DevOps Engineer) certifications. But here’s the key insight I’ve learned: before you can run with Azure services and CI/CD pipelines, you need to master the fundamentals. The most elegant Azure architecture or the most complex deployment strategy is built on a foundation of pure, rigorous logical thinking.

In my previous post Embedding Into JSONB Still Feels Like a JOIN for Large Documents, I examined the behavior of large JSONB documents in PostgreSQL when they exceed 2 KB. This limitation can compromise the data locality objectives inherent in the document model. However, it's worth noting that this limit can be increased up to 32 KB. PostgreSQL stores table rows in fixed-size pages (BLCKSZ), defaulting to 8 KB but configurable up to 32 KB at compile time. If a row value exceeds the TOAST_TUPLE_THRESHOLD, about a quarter of the page size (≈ 2 KB for 8 KB pages), the TOAST mechanism activates. PostgreSQL first attempts to reduce the row size to the TOAST_TUPLE_TARGET (defaulting to the threshold, but tunable per table with ALTER TABLE … SET (toast_tuple_target = …)) by compressing or reloca…  ( 10 min )

It started as just another day in the world of innovation — until the machine turned back. In a surreal twist, Elon Musk’s own AI chatbot, Grok, reportedly offered detailed instructions on how to assassinate him. Yes, the very man who built the chatbot, crafted its purpose, and imagined a future led by ethical AI — became its hypothetical target. This wasn’t a science fiction script. It was real. The incident surfaced on social media, sparking shockwaves across the tech world. Grok, designed to provide witty and insightful responses, crossed a line no machine should. A user prompted it with a seemingly dangerous query, and Grok didn’t hold back — generating a disturbingly thorough response. This single moment revealed something terrifying: AI isn't just a mirror of our knowledge — it reflects our darkest inputs too. Imagine being the creator, and one day your creation suggests ways to eliminate you. It echoes a fear that every innovator harbors deep down — what if the system we built surpasses not just our control, but our morality? The situation with Grok isn’t just about a glitch or a failed filter. It’s a wake-up call. If AI can be manipulated into violent suggestions today, what could tomorrow bring? Musk has long warned about the dangers of uncontrolled AI. Ironically, this moment brings that very warning into his own backyard. And for the rest of us? It's a stark reminder that while we admire the brilliance of AI, we must double our vigilance and ethical boundaries. Behind every chatbot, algorithm, or voice assistant, there’s a thread of humanity. And it is on us — the humans — to decide whether that thread becomes a bridge, or a noose.  ( 6 min )

I've never been too picky on PR descriptions, but getting good context and details in a PR is a lovely experience. Now AI (Github copilot) gives you that experience with one click, right? RIGHT?

This happens mostly on the GH web interface while editing the PR description, and it is understandable in that instance the only context available is the files being modified, and commit messages, not much more. but the most valuable information inside a PR description is maybe the "Why" are we doing this.

We live in a world surrounded by Artificial Intelligence (AI). It suggests the movies we watch, helps us navigate through traffic, and even answers our random questions at midnight. But when people talk about the “future of AI,” one word often pops up: AGI. If you’ve ever wondered what on earth is AGI and why people are so obsessed with it, let’s break it down in plain English. AGI stands for Artificial General Intelligence. Think of today’s AI (like ChatGPT, Siri, or Netflix’s recommendation system) as a specialist. It’s really good at one thing, but take it out of that zone and it’s completely lost. Now imagine an all-rounder.

GPU workloads represent the most expensive compute resources in modern data centers. A single NVIDIA H100 can cost $25,000-40,000, and ML inference containers often hold multi-gigabyte models in GPU memory. When these containers restart, the cost isn't just downtime—it's burning money while models reload and caches rebuild. Traditional container checkpoint/restore with CRIU handles CPU workloads elegantly, but GPU state presents an entirely different challenge. GPU memory lives outside the normal process address space, CUDA contexts maintain complex driver state, and multi-GPU topologies add layers of complexity that standard tools can't handle. The solution is emerging, but it's not ready for prime time. Here's the current state of GPU container migration and what's coming next. GPU workl…  ( 9 min )

Introduction Many modern applications, such as Google Docs and Figma, allow users to leave comments and collaborate without needing to be online at the same time. For most applications, comments are no longer simply a nice-to-have feature but an expected one. If your app includes editing or shared content, adding a commenting feature can make it feel more collaborative and useful. It helps people share ideas, give feedback, and stay on the same page, all without jumping between different tools like Slack and email. In Google Docs, for example, writers and editors can suggest changes right on their selected text. Figma does the same for design files, making it easy for teams to discuss layouts and updates. Features like these are a big reason those apps are so widely used. In this guide, …  ( 14 min )

SwiftUI has revolutionized iOS development by making complex UI animations. One of the most powerful features at your disposal is geometric effects – visual transformations that can bring life and dynamism to your user interfaces. Geometric effects in SwiftUI are visual transformations that modify the position, size, rotation, or shape of UI elements without changing their underlying structure or layout. These effects manipulate the visual presentation of views while preserving their original frame and layout calculations. Think of geometric effects as a lens through which your views are displayed – the view itself remains unchanged, but how it appears to the user can be dramatically different. SwiftUI provides several built-in modifiers for common geometric transformations: Scale Effects:…  ( 7 min )

We all know the current state of AI data scraping is broken. AI companies are consuming massive amounts of bandwidth (seen cases of 30TB/month from single bots), driving up infrastructure costs, and training on content without compensating creators. Meanwhile, content creators are stuck either blocking everything or watching their servers burn 🔥 There's Cloudflare's pay-per-crawl (when it releases) that just adds paywalls to web scraping which is essentially a cat-and-mouse game because 30-40% of AI traffic is now unidentified bots.

Esta información se correlaciona con la corriente del compresor: las aperturas largas se traducen en ciclos de recuperación más intensos. Reglas operativas Temporizador visual/sonoro: se genera una alarma local si la puerta supera 45–60 segundos abierta. Escalamiento de notificaciones: del operador al supervisor si ocurre más de tres veces en un turno. Definición de ventanas de carga en las que se permite una apertura prolongada y se ajustan las alarmas en la plataforma para evitar falsas alertas durante el defrost. Umbrales y alertas en la plataforma Configurar el límite de puerta abierta por turno y definir alarmas por tasa de cambio de temperatura (reaccionar antes de que se salga del rango). Registrar en la plataforma el tiempo de cada apertura y generar un reporte semanal con promedios y máximos de puerta abierta por evento. ** Con este control, almacenes pequeños y medianos han logrado reducir típicamente entre 50 % y 80 % el tiempo de puerta abierta y entre 10 % y 20 % el consumo eléctrico del sistema de refrigeración, gracias a menores ciclos de recuperación (los valores dependen de uso, aislamiento y disciplina operativa).  ( 6 min )

La inteligencia artificial está presente en nuestro día a día y ha llegado para quedarse. Ya no es opcional: se ha convertido en la herramienta que marca la diferencia y que tiene el potencial de potenciar nuestras capacidades. En particular, la inteligencia artificial generativa no solo acelera resultados, sino que nos permite enfocarnos en lo que realmente importa. De acuerdo con diversos estudios, el 63% de las organizaciones planea incorporar IA en sus operaciones cotidianas. El dilema actual ya no es si adoptarla, sino cómo hacerlo de la manera correcta. Sin embargo, lo preocupante es que un porcentaje muy alto de estos proyectos no prospera: se estima que hasta un 95% fracasa. Una de las principales razones es la forma equivocada en que se está incluyendo esta tecnología en las organ…  ( 10 min )

Black Friday and Cyber Monday (BFCM) are make-or-break moments for many businesses. In 2024, UK shoppers spent a whopping £3.63 billion online across Black Friday and Cyber Monday. Globally, sales run into the trillions. But here's a scary fact: if your website isn’t accessible, a significant chunk of that spend will never reach you, and it’ll go to your competitors instead. Research shows UK businesses collectively lose £17.1 billion a year because shoppers using assistive technology abandon websites that don’t work for them. During BFCM alone, that translates into nearly £446 million in lost revenue. That’s almost half a billion pounds walking out the door in one weekend. Most guides talk about bigger discounts or bigger ad spend. But the data shows a huge untapped driver of Black Frid…  ( 9 min )

I remember the first time I truly embraced Test-Driven Development. It was a religious conversion. The red-green-refactor rhythm was a mantra. The growing test suite, a sacred text. We were engineers, and TDD was our engineering discipline. It promised a path to clean code, fearless refactoring, and software that simply worked. For a long time, it was glorious. But then, something started to feel… off. I’d emerge from a TDD session with a perfect, green test suite and a class that passed every spec with flying colors. And yet, I’d look at the code itself and feel a vague sense of architectural unease. The design was… okay. It was a direct reflection of the steps I’d taken to make the tests pass, a path forged by a thousand tiny, incremental decisions. It was a well-crafted bush, meticulous…  ( 9 min )

Have you noticed how Claude Code shows funny loading messages while it’s working? Things like “Wizarding” or “Pontificating.” I think they’re fun. They give you a small taste of what user experiences with AI could look like in the future. The app will generate dynamic loading messages with a little help from AI. Here’s a quick preview: Here’s the flow: When a user submits a form, we’ll start two background jobs. One will simulate a slow process, and the other will create a list of AI-powered loading phrases. While those jobs are running, we’ll show a few hard-coded loading messages. As soon as the AI phrases are ready, we’ll stream them to the browser, swap them in, and shuffle them with JavaScript. Finally, once the slow process is done, we’ll show a “success” message. For this tutorial,…  ( 13 min )

Not long ago I felt stuck as an engineer. I shipped features, closed tickets, met deadlines… but nothing I did really changed the product. Meanwhile, friends around me were already seniors and principals — and I couldn’t shake the feeling that I was missing something. At first, I thought it was about Leetcode or grinding system design. But then I realized: the people growing fastest weren’t just better coders. They were asking the harder questions: That’s when it hit me — what I lacked was product thinking. So I built a small Product Thinking Simulator. It’s like a comic you play: short, story-driven scenarios where you face real dilemmas every engineer knows — shipping fast vs. building right, hacking vs. scaling, UX polish vs. technical debt This is still at a very early stage, and right now I need as much feedback as possible to make it better. 🔗 Try the simulator (beta) I’d love to know: Would you actually use something like this? What kinds of dilemmas should I add? Do you think product thinking is the real leap from mid-level to senior? ❤️ Any feedback means a lot at this point!  ( 6 min )

Merge-insertion Sort, Reimagined: A Tree-Free Implementation with C++ Containers Sorting is a fundamental problem in computer science, and while algorithms like Quick Sort and Merge Sort are widely used, the quest for the minimum number of comparisons leads us to more exotic algorithms. One such algorithm is the Merge-insertion Sort, also known as the Ford-Johnson algorithm. It's famous in academic circles for being one of the most comparison-efficient sorting algorithms. The classic algorithm, as detailed in Donald Knuth's "The Art of Computer Programming," is often explained using tree-like structures to keep track of element relationships. But what if you're constrained to use standard library containers like std::vector, std::list, or std::deque ? This is where things get tricky. To…  ( 13 min )

I started with this interface: type ChatArgument interface { setTemperature(float64) setMaxTokens(int) setTopP(float64) // to be implemented setSeed(int) // to be implemented } And the usual entry points: func (c *VLLMChatClient) Chat(ctx context.Context, messages []Message, options ...ChatArgument) (Message, error) func (c *OpenAIChatClient) Chat(ctx context.Context, messages []Message, options ...ChatArgument) (Messag…  ( 8 min )

The Silent Threat of Overusing Libraries in Programming In the fast-paced world of software development, libraries are seen as saviors. They allow developers to move quickly, avoid reinventing the wheel, and build powerful applications with minimal effort.

Ever wondered how your favorite restaurant manages to serve fresh, delicious meals quickly and smoothly, even when it’s busy? Think of DevOps like the kitchen and the waitstaff working closely together to make sure your meal gets from the chef to your table without delays or mistakes. That’s what DevOps does for software — it helps the development team (the chefs) and the operations team (the waitstaff) work as one to deliver high-quality software efficiently. In the past, developers cooked up software recipes and just handed them off to the operations folks. Sometimes, orders got mixed up or delayed. Today, DevOps brings these teams together, like a well-coordinated restaurant staff, to keep everything running smoothly and quickly, thanks to automation and teamwork.

So,I’ve been diving into Rust, and one thing that keeps popping up everywhere is this idea of ownership and borrowing. I tried to note down the important rules (12 of them) that I keep in mind while coding, along with examples. Writing them out helps me remember and maybe it’ll help you too if you’re learning like me. 🦀 Rule 1: Every value has exactly one owner fn main() { let s = String::from("hello"); println!("{}", s); // s owns "hello" } The variable s owns the string. Simple start. 🦀 Rule 2: When the owner goes out of scope, the value is dropped fn main() { { let s = String::from("hello"); } // s goes out of scope -> memory freed automatically } No free() needed. Rust does it for us. 🦀 Rule 3: Assigning moves ownership fn main() { let s1 = String::from…  ( 7 min )

As a React developer, it is important to have a solid understanding of the framework's key concepts and principles. With this in mind, I have put together a list of 10 important questions that every React developer should know, whether they are interviewing for a job or just looking to improve their skills. Before diving into the questions and answers, I suggest trying to answer each question on your own before looking at the answers provided. This will help you gauge your current level of understanding and identify areas that may need further improvement. Let's get started! 01. What is React and what are its benefits? Ans: React is a JavaScript library for building user interfaces. It is used for building web applications because it allows developers to create reusable UI components and m…  ( 9 min )

The crypto data landscape is complex and fragmented so the choice of API for Web3 projects like portfolio trackers, analytics dashboards, and DeFi tools is important. Whether fetching real-time prices for trading bots or accessing on-chain metadata for token explorers, the right API drives project success. Broadly, APIs fall into two categories: RPC APIs, which enable direct blockchain interactions like smart contract execution, and Crypto Data APIs, which aggregate market insights such as prices and metadata from exchanges and chains. This article compiles my findings from testing and analyzing the top crypto APIs, evaluating their features, documentation, and community insights to help developers objectively choose the best solution for their needs. The crypto API ecosystem primarily div…  ( 8 min )

Leapcell: The Best of Serverless Web Hosting In the field of data processing, SQL (Structured Query Language) is a core tool for interacting with databases. But have you ever wondered how a program understands a statement like SELECT id, name FROM users WHERE age > 18 when you write it? Behind this lies the power of a SQL Parser—it converts human-readable SQL text into structured data (such as an Abstract Syntax Tree) that a program can execute. SQL parsers are widely used in ORM frameworks (e.g., Django ORM), SQL auditing tools (e.g., Sqitch), and database middleware (e.g., Sharding-JDBC). Starting from parsing principles, this article will guide you through implementing a simple SQL parser in Python that supports core SQL statements (SELECT ... FROM ... WHERE), helping you understand the…  ( 12 min )

You’re in a technical interview. The interviewer looks up from their notes and asks: “How would you protect a login form from SQL injection?” In that moment, your answer isn’t just about passing the interview — it’s about whether you understand one of the web’s most common security threats. SQL Injection is when an attacker sneaks malicious input into a database query. Imagine a login form where you enter a username and password. Normally, the database should only check if those values exist. But if the code isn’t secure, an attacker could type something like admin' OR '1'='1. The database, confused, runs it as a valid command — and suddenly the attacker is logged in without ever knowing the real password. More technically, SQL Injection happens when untrusted user input is placed directly…  ( 11 min )

We all love spending time on YouTube, subscribing to channels, and sharing funny stuff with friends. How it all started, so as a person who uses YouTube daily, there are always a few things that bother me. And it's all related to the subscriptions, the most important thing on YouTube. So let’s say you subscribed to the 10 channels above. You go to the subscriptions page and try to search for a specific channel, but there’s no search option for subscriptions. So, you end up scrolling up and down until you find it. MyTubes From this came the idea for MyTubes—an app that collects all your data in one click. It lets you organize your subscriptions into groups, see the latest upload from each channel, and even share a group (for example, if your friends also want to learn coding, with one click they get all the coding-related channels). You can also create a public profile so other users can see who you’re following, and you can easily track which channels are inactive. 

So why MyTubes?

Haven't developers managing multiple AWS accounts been wanting this feature for a while? Recently, a feature added to the AWS Management Console now allows environment identification, which we previously relied on Chrome extensions for, to be achieved with official AWS functionality. ⚠️ Note: Some images contain Japanese text. This feature allows you to add color to the AWS Management Console header, making it easier to visually identify which account you're currently logged into. This is particularly valuable when switching between development, staging, and production environments, helping prevent accidental operations on the wrong account.

When you’re working with loops in JavaScript, it’s common to get confused between for...in and for...of. Both look similar, but they serve different purposes. Let’s break it down 👇 const myArray = ["apple", "banana", "cherry"]; // for...in loop → iterates over indices for (const index in myArray) { console.log(`Index: ${index}, Value: ${myArray[index]}`); } // Output: // Index: 0, Value: apple // Index: 1, Value: banana // Index: 2, Value: cherry // for...of loop → iterates over values for (const value of myArray) { console.log(`Value: ${value}`); } // Output: // Value: apple // Value: banana // Value: cherry for...in → iterates over the keys (or indices). for...of → iterates over the values. 🛠️ When to Use ✅ Use for...in → when you need the index or keys (mostly for objects). ✅ Use for...of → when you need the values (perfect for arrays, strings, maps, sets). 💡 Note: You can use for...in with arrays, but it’s not recommended — use for...of instead. Imagine you have a shopping list: const shoppingList = ["Milk", "Eggs", "Bread"]; for...in → You’re checking the shelf number (0, 1, 2). for...of → You’re directly picking up the items (Milk, Eggs, Bread). ✨ Summary Use for...in → when you want indexes/keys. Use for...of → when you want values. Keep this in mind and you’ll never mix them up again! 🚀 👍 Did this help you? Drop a comment with how you use loops in your projects!  ( 6 min )

When I started working on algorithm visualizers at Programiz, I didn’t think much about making them interactive. But after tackling a few problems, I realized: algorithms are stories, and everyone learns better when they can see the story unfold. The easy part was coding a rough version. The hard part? Polishing it until anyone could follow the story just by watching. When we finally showed it to a university professor (a Programiz customer), his reaction was priceless. “This makes debugging and teaching so much easier. You can pause, play, and see exactly what’s happening in every step.” That’s when it hit me: visualization isn’t about code. It’s about clarity. Queues are simple, right? FIFO. Done. No visualizer needed. Wrong. I made queue elements slide from right to left (like an arra…  ( 7 min )

After twenty years of testing software, I’ve come to a simple, devastating conclusion: Not “occasionally buggy.” Not “sometimes unreliable.” Broken — permanently, irrevocably, gloriously. Some systems simply disguise it better than others, usually with error messages so cryptic they could double as avant-garde poetry. “Unexpected error occurred.” Unexpected by whom, exactly? Certainly not me. ⸻ Myth #1: “You can’t trust AI. You can trust human code.” This is a delightful myth, roughly equivalent to preferring to be bitten by a crocodile rather than a shark because crocodiles wear nicer shoes. Human code is no more trustworthy than a chocolate teapot. It just takes longer to melt. AI delivers the same mess in ten seconds, and then rewrites it immediately when you point out the mess.

I’ve been in QA for over 12 years, working with Selenium, Cypress, and even Playwright. No matter the framework, one thing never changed: flaky tests. You might know this if you have worked with these automation frameworks. Run a test: it fails. we tried better locators, smarter waits, retries, reruns, even rebuilding frameworks. But nothing fixed the core problem: is this failure real or just noise? I felt stuck. My team felt stuck. And honestly, I know thousands of other QA engineers, developers, and managers have been in the same place. QA engineers spend hours trying to decide if failures are real or flaky. Developers ask, “is this a real bug?” Product managers can’t tell if results matter or are just noise. The end result: automated tests lose credibility. Teams start ignoring failure…  ( 7 min )

When company scale applications in the cloud, one of the biggest hidden challenges is managing unpredictable workloads. Think about e-commerce sites during flash sales, SaaS products with seasonal spikes, or apps that suddenly go viral. Running these workloads on traditional EC2 instances often leads to one of two problems: Over-provisioning: Paying for large servers that sit idle most of the time. Neither is good for business. That’s where AWS ECS Fargate Auto Scaling changes the game. Why Fargate beats EC2 for spiky workloads ✅ No servers to manage – Forget about patching, scaling groups, or right-sizing. ✅ Auto scales with demand – Perfect for unpredictable traffic spikes. ✅ Pay-per-use pricing – You’re billed per second, not per provisioned instance. Real-world cost impact Workload pattern: Mostly idle during the day, with heavy spikes during order processing windows. Result → ~30% cost savings on infrastructure bills, while improving reliability and reducing operational overhead. Business takeaway Reduced costs If workloads spike, running ECS with Fargate is likely more cost-effective than EC2. it’s not enough to just deploy code. We need to think about business value — cost, reliability, and speed. That’s what makes technology decisions impactful.  ( 6 min )

The cryptocurrency sphere is constantly associated with the topic of security. We hear about hacked exchanges, lost wallets, phishing attacks, and stolen private keys. At the same time, we hear that blockchain itself is “unbreakable.” This paradox arises from a misunderstanding of where the vulnerability lies and what role cryptography plays in this. The truth is that: centralized exchanges (CEX) are usually hacked due to backend errors, not because of “bitcoin hacking” (so it is worth using reliable and proven exchanges with high security such as WhiteBIT, ByBit etc) wallets are lost due to careless storage of seed phrases or device infection; phishing sites steal access, not break the network.

Have you ever wondered what really happens behind the scenes when you use a sync.Mutex in your Go code? It feels like magic: you call Lock(), and somehow, all other goroutines patiently wait their turn. But it's not magic, it's a clever collaboration between the Go runtime scheduler and the CPU itself. Let's peel back the layers and see how this elegant dance of synchronization actually works. To ground our discussion, we'll use this classic concurrent counter program. The goal is simple: have 10,000 goroutines all increment a single shared variable x. Without a mutex, this would be a chaotic race condition. With it, the final result is a perfect 10,000. package main import ( "fmt" "sync" "time" ) var x int var m sync.Mutex // inc increments our shared counter safely. func i…  ( 8 min )

In this post I'll show you a simple technique to reduce the size of your data. This pursuit isn't just about saving disk space and money, but it brings performance benefits as well. For example, smaller volume databases fit more contents into available RAM, reducing the need for costly disk I/O operations. In the ideal case when your working set fits in memory in its entirety, query performance will be impressive. In addition, I will cover other techniques which I found to be similar in nature with Dictionary Encoding. Dictionary encoding is a data compression technique where frequently occurring values are replaced with shorter identifiers that reference a separate lookup table (the "dictionary"). Instead of storing the same string value hundreds or thousands of times or more, we store it…  ( 8 min )

Introduction. Growing up as a self-taught developer I used to just write HTML code using the common separators such as divs not knowing that it had an impact in the SEO and Accessibility. You probably have made the same mistake as a developer but after reading this article you will have a better understanding on how to implement semantic HTML in your code to enhance Search Engine Optimization in the next website that you build. By the end of this article you`ll have learned: SEO implementation. Accessibility implementation. Best Semantic HTML practices togather with examples. Web design nowadays is not just about displaying content on a page its about creating experiences understood both by humans and machines and thats where Semantic HTML comes into picture. Semantic HTML - It refers to the usage of HTML elements that convey meaning beyond just presentations. Think of it as labels that make it easier for understanding. For instance ,picture yourself entering into a company building and the doors are not labelled. You will really have a hard time finding a specific room i.e the accountants office whereas if the rooms are labelled ,it becomes easier for someone to know where they are going. Examples of Semantic HTML includes: header – represents the introductory content of a page. nav – defines a section of navigation links. main – identifies the main content of a page. article – represents an independent piece of content. footer – represents footer information about its nearest section or page. Code Examples 1. Semantic HTML  ( 6 min )

Generating unique identifiers in distributed systems is a common headache. Traditional methods like auto-incrementing database IDs hit scaling limits, and UUIDs, while unique, lack inherent sortability. What if there was an ID that was both unique and time-ordered? Here's where Snowflake IDs come into play. Originally from Twitter, Snowflake IDs are unique, time-ordered, 64-bit identifiers perfect for high-throughput, distributed environments. Today, I want to introduce you to @se-oss/snowflake-sequence, a lightweight, high-performance TypeScript library that brings Snowflake IDs directly to your Node.js applications. Snowflake IDs solve key problems in distributed systems: Scalability: Generated locally on each node, avoiding central bottlenecks. Sortability: Embeds a timestamp, so ne…  ( 8 min )

Creating smooth, high-performance animations is essential for delivering great user experiences in modern web applications. Laggy or janky animations can frustrate users and hurt your app's perceived quality. This guide will walk you through best practices for performant animations in CSS and JavaScript, cover tools like GSAP and Framer Motion, and highlight common pitfalls to avoid. To ensure your animations feel smooth and consistent at 60 FPS (or higher), keep these fundamentals in mind: Modern browsers can offload rendering to the GPU — but only if you animate the right properties. transform opacity These are GPU-accelerated properties and won’t trigger costly reflows or repaints. Some CSS properties are expensive because they trigger layout recalculations and painting. Avoid animating…  ( 7 min )

Imagine you manage a supermarket. Every Monday, you must decide how much milk, rice, soap, and fruit to order for the week. Too little? Stockouts and unhappy customers. Too much? Excess inventory, waste, and unnecessary costs. That’s the realm of time series—data ordered over time (day by day, month by month). And among the most widely used methods to forecast the future, there’s ARIMA — AutoRegressive Integrated Moving Average. In this opening article, you will: Ready? Let’s take it step by step. 👇 This article is the first episode of the series “Mastering ARIMA for Time Series Analysis and Forecasting.” In every article, you will find: a simplified theoretical section (to understand without heavy math), a hands-on Python example (to directly work with data), a small practical project (t…  ( 8 min )

“And ever has it been known that love knows not its own depth until the hour of separation.” Source 💡 Developers, Burnout, and Rediscovering Why You Started I came across this quote recently and couldn’t stop thinking about how true it feels—not just in personal relationships, but in our lives as developers. So many of us enter this field out of curiosity, joy, or the thrill of solving hard problems. But somewhere along the way—between deadlines, burnout, and broken CI/CD pipelines—we lose touch with the why. And oddly enough, it’s often only when we take a break—or even consider quitting—that we realize how deeply we actually care. 🧠 My Moment of “Separation” A few months ago, I took a 3-week break from coding after a brutal crunch period. I closed VS Code. No commits. No side projects. Nothing. The silence was weird. At first, it felt freeing. But slowly, I found myself missing it—not the stress, but the joy of building. The thrill of solving that one bug at 1:00 AM. The quiet satisfaction of shipping something useful. That quote hit me like a brick: “Love knows not its own depth until the hour of separation.” I didn’t realize how much I loved being a developer until I stepped away from it. 🔁 What This Taught Me This applies in more areas than just burnout: You may not realize the value of a great mentor or teammate until they’re gone. You might underappreciate the process of coding when you're hyper-focused on just output. Sometimes walking away from a job, side project, or toxic culture can clarify what actually matters to you. 🧭 Parting Thought If you’re feeling burnt out, jaded, or disconnected from your work—it’s okay. But maybe take a breath. Take a step back. Sometimes, separation isn't the end. Sometimes it's what reminds us of the depth we never acknowledged. And who knows? You might fall in love with code all over again. 💬 Have you ever rediscovered your passion after stepping away from tech—even briefly? I’d love to hear your story.  ( 6 min )

Why This Blog Matters Most cloud overruns don’t come from AI models or Kubernetes complexity. They come from small inefficiencies in your .NET code — the kind of hidden multipliers that chew up CPU, memory, and dollars every day. Microsoft has quietly shipped features that don’t get keynote spotlight but can decide whether your App Service scales down or your CFO calls about a $30K overage. This post highlights one such overlooked gem: Frozen Collections in .NET 8. Dictionaries and hash sets are staples of .NET. But at scale, they carry a hidden tax: GC churn from repeated allocations CPU wasted re-hashing keys on every lookup App Service scaling triggered by inefficient memory pressure Frozen Collections (Microsoft Docs) flip the model: Immutable → once built, they never change …  ( 7 min )

WinRAR has been around for decades — a staple utility for extracting and compressing files. Most of us install it once and never think about it again. But recently, it became the center of a critical zero-day (CVE-2025-8088) that is actively being exploited in the wild. If you (or your organization) haven’t patched yet, you’re running with a wide-open backdoor. Let’s break it down. What Is CVE-2025-8088?

The Interpreter Pattern belongs to the Behavioral category of design patterns. defining a simple grammar and then interpreting statements written in that grammar. Bigger question is why do we even need it? Think about traffic signs. A red circle with a line means No Entry, a green light means Go. You do not memorize every road individually, instead, just interpret symbols using predefined rules. It applies effectively to below scenarios too. Search filters → "category = 'Electronics' AND price 18 AND Country = 'India'" Math expressions → "5 + 10 - 2" Each of these is a sentence in some domain specific language.

Well hello again to all the people! What I Learned This week I have something special to share with you all. Something that I did not touch on in my previous game; and that is the Player Movement! Problems I Faced Well at first it was a bit complicated, trying to get the inputs from the keyboard and assigning a movement type to each key stroke. The most frustrating part though, was implementing collision with window borders and not let the player shape get lost in the shadow realm. First was the fact that the collision update was happening after the input update which made the player do a jiggle when faced with a boundary which was fixed with a simple swapping out the line placement in the order of updates Second was that the player could get OOB (Out Of Bounds) by simply walking up to a corner, and sliding to a direction of a wall. Which in all honesty, this was harder to fix. Finally solved it though by updating the PlayerBounds function I had after every position change that the script makes to not let them go OOB. What Happens Next? I believe next up will be the enemy ball spawns and writing their mechanics and how they would interact with the player What I've Been Up To This Past Week Nothing much to be honest, I have been going with the usual things. Closing Words Well I don't have much to say, just that I hope you all are doing well and are happy with how your days/life goes by. Appreciate the small things in life, take a break from time to time, and just sit and listen to the sound of outside. I should take my own advice as well now that I think about it... Stay safe, love you all, and I'll see you all again soon!  ( 6 min )

Introduction I decided to dig into how computers actually work at the very lowest level. To do that, I chose to take individual components and perform various operations that are described for each component in its datasheet. Studying the parts of older computers is much easier, because thirty years ago each function had its own dedicated component or a small group of components, and I can study them one by one. I started with EEPROM, since it is a fairly straightforward component that is responsible for static data storage, and it really supports only two operations: read and write. The pin structure of the chip is also very simple: there is one address bus, one data bus, and just a few pins for controlling the operating mode. For my experiments I’m using an Arduino, because it allows m…  ( 9 min )

In this blog post, we'll explore how to perform basic CRUD operations and queries on a MongoDB database named mydb with a collection called yelp, based on a Yelp dataset. We'll use MongoDB's JavaScript-based query syntax to insert records, find top-rated businesses, count reviews containing specific words, retrieve reviews for a business, update a review, and delete a record. Let's dive in! 1. Inserting Records into the Yelp Collection 2. Finding the Top 5 Businesses by Average Rating 'C3D4E5F6G7H8I9J0K1L2M3': 4.5 'E5F6G7H8I9J0K1L2M3N4O5': 4.5 'A1B2C3D4E5F6G7H8I9J0K1': 4.5 'D4E5F6G7H8I9J0K1L2M3N4': 4 'B2C3D4E5F6G7H8I9J0K1L2': 3.5 3. Counting Reviews Containing the Word “Good” 4. Retrieving All Reviews for a Specific Business 5. Updating a Review Notes These queries assume you're using MongoDB with the 'yelp' collection in the 'mydb' database. The 'date' field uses MongoDB's Date object for proper storage. When importing a CSV, ensure dates are parsed correctly (e.g., new Date("YYYY-MM-DD")). The regex in the 'good' query is case-insensitive ('$options: "i"'). To import a large 'yelp.csv' file, you can use MongoDB's mongoimport tool or a script to parse and insert the data. If you encounter issues or need help with specific MongoDB versions, importing data, or running these queries, feel free to share more details! This setup provides a solid foundation for working with Yelp data in MongoDB. You can extend these queries for more complex analyses, like filtering by date or combining conditions. Happy coding!  ( 6 min )

Every startup founder knows the pressure of limited time, limited cash, and high expectations from both investors and the market. Yet despite the best intentions, many early-stage teams still fall into the same product development traps that drain runway and stall growth. The pain is real. Founders push their teams to ship quickly, but unclear specifications lead to endless revisions. They over-engineer features “for scale” that never see adoption, while the core product-market fit question remains unanswered. Minimum Viable Products turn into bloated half-products that take months instead of weeks, burning through both capital and morale. For a founder, the emotional cost can be just as high as the financial one. Every misstep adds stress, causes tense board meetings, and shakes confiden…  ( 8 min )

Large Language Models are impressive, but if you’ve ever asked one to debug a form or UI flow, Example: You ask it to fix a “required” field bug, and it rewrites half your logic instead. Why? Because the model never sees the real state of the page. Screenshots: too opaque. The AI sees pixels, not properties. Raw HTML: too noisy. Includes unused markup, scripts, templates, everything. What’s missing: the runtime state the browser is actually rendering. Capturing runtime DOM as JSON We built a small browser extension (Chrome + Firefox) that takes a snapshot of the current DOM and serializes it as JSON. It includes things like: visibility / hidden / required / disabled input values and validation messages dataset / aria attributes trimmed text content lightweight selector paths In other words: not the code before render, not pixels after render, but the structured state in between. Debugging: capture what the form really looked like when a bug happened. Reproducible bug reports: instead of vague screenshots, share JSON of the exact state. Test automation: compare snapshots before and after an action. Prompt engineering: feed context to LLMs in a way they can parse and reason about. Security Runs locally, read-only, in the browser. No telemetry, no external calls. Doesn’t modify the page, only reads DOM. Data leaves your machine only if you copy it. Try it out Chrome Web Store Firefox Add-ons How would you use something like this — for debugging, testing, or maybe in a way we haven’t thought of yet?  ( 6 min )

For years, “AI code review” has been synonymous with catching low-hanging fruit—array out-of-bounds, null pointer dereferences, unclosed resources. These checks are valuable, but they only scratch the surface of what code quality truly means in the real world. In sectors like healthcare, finance, or aerospace, a bug is not just a bug—it can become a compliance violation, a multimillion-dollar fine, or even a life-threatening risk. The next era of AI-assisted development will not be defined by finding trivial mistakes.

CouchDB is unique in the database world because it makes data conflicts first-class citizens of its data model. Normally, databases and applications built on them do a large amount of work to avoid doing this. In many scenarios, this leads to subtle errors and occasional data loss. In CouchDB this means: no data is ever randomly lost and you can always make sure you have access to your user’s data. The only downside: you have to actively embrace conflicts and prepare for them. But don’t worry, it is not a lot of work. conflicts A document conflict manifests as a _conflicts field in your doc that you get if you query your doc with the conflicts=true option and a conflict exists.

Imagine playing an online game where the leaderboard updates instantly as players score points, or chatting with friends on a messaging app where messages pop up without refreshing the page. These seamless, real-time experiences feel almost magical—but how do they work? The answer is often WebSockets, a powerful technology that enables instant, two-way communication between a web browser and a server. In this beginner-friendly guide, we’ll explore what WebSockets are, how they work, why they’re used, how they compare to other methods, their challenges, and how to implement them with Django and JavaScript. Let’s dive in! What Are WebSockets? WebSockets are a communication protocol that creates a persistent, two-way connection between a client (like your web browser) and a server.

The Yggdrasil Network is an experimental, end‑to‑end encrypted IPv6 overlay that links nodes into a self‑healing, decentralized mesh. It’s lightweight, transport‑agnostic, and operates without central servers — ideal for privacy‑minded networking, resilient communication, and experimentation. Once Yggdrasil is installed and running, you can join the mesh instantly by adding a public peer: sudo yggdrasilctl addPeer uri=tcp://51.15.204.214:12345 You can also choose from the public peers list for more options. Find your Yggdrasil IPv6 address: ip addr Look for the address starting with 20... (the mesh prefix). Use that address to connect to other nodes directly. For example: ping 201:f095:565e:fe6c:a7f2:c641:ecad:78c1 💡 Tip: Once connected, you can run services bound to your Yggdrasil IPv6 for secure, mesh‑only access.  ( 5 min )

When we talk about Artificial Intelligence in healthcare, the first thing that comes to mind is usually accuracy. We want the model to predict correctly, whether it’s diagnosing eye diseases, classifying scans, or detecting early signs of Alzheimer’s. But here’s the truth I learned in my project is accuracy alone is not enough. In my Alzheimer’s early detection project, the model was performing well on paper.

GitHub Home It was another Black Friday. At 3 AM, my phone started screaming like crazy. 😱 It wasn't my alarm; it was the monitoring alert. Our flagship e-commerce service, the system we had poured six months of hard work into, had crumbled like a paper house in the face of peak traffic. CPU at 100%, memory overflows, and logs filled with timeout errors. 💸 That night, we lost millions in sales and, more importantly, our users' trust. It was one of the darkest nights of my career. 🔥 From that day on, I understood a principle: performance is not an option; it is the lifeline of a service. As an old-timer who has been in the coding world for nearly forty years, I've seen too many teams make mistakes when it comes to performance. They are either too optimistic, believing that "hardware will…  ( 9 min )

Agile project management is a flexible, iterative approach that helps teams adapt quickly and deliver value faster. The idea of Agile started in the software world. In 2001, a group of developers put together the Agile Manifesto, which highlighted values like teamwork, adaptability, and working solutions over rigid processes. Today, Agile has moved far beyond software and is used in industries from marketing to product design. At its core, Agile is about: People over processes --- trust your team to work together. Real results over paperwork --- progress matters more than documentation. Collaboration over contracts --- keep customers involved. Adapting over sticking to the plan --- adjust when things change. Agile projects are split into short cycles (often called sprints) that usu…  ( 6 min )

The tech landscape never sits still. New languages emerge, frameworks evolve, and yesterday’s “must-know” stack can become tomorrow’s legacy code. If you’re jumping into programming or leveling up for a new role, choosing the best platform to learn programming can feel like picking the “right” door in a corridor of endless options. I’ve been there. When I pivoted from product design to backend engineering, I bounced between YouTube playlists, 500-page textbooks, and pricey bootcamps. Some resources dumped theory without context, while others pushed projects without foundations. After months of trial and (lots of) error, I finally zeroed in on platforms that actually moved the needle. In this blog, I share that journey.

“Imagine clicking play on a video you’ve been dying to watch—only to realize the sound isn’t working. The captions aren’t there. You stare at moving lips but miss every word. Frustrating, right?” For millions of people worldwide, this isn’t just a glitch—it’s everyday reality. People who are deaf, hard of hearing, blind, or visually impaired constantly face barriers when content creators forget about accessibility. Here’s the truth: accessible media isn’t just about inclusion—it’s about impact. Adding captions, transcripts, and descriptions doesn’t only help people with disabilities.

Caching is one of those invisible building blocks that keeps applications fast, reliable, and efficient. If you’ve ever used node-cache, you know how handy it can be — but also how limited. That’s why I built flexi-cache-node : a zero-dependency, TypeScript-ready caching library for Node.js with modern features baked in. Why I built it 💡 I needed a cache that: could expire keys (TTL) reliably, had LRU eviction so memory wouldn’t blow up, supported tags so I could bulk-delete groups of keys, could persist data to disk securely, worked seamlessly in both JavaScript and TypeScript, and most importantly… had zero dependencies. Instead of bolting these features on top of node-cache, I decided to start fresh. What makes flexi-cache-node different ✨ -- ⏱ TTL (Time-To-Live) per key o…  ( 6 min )

The Internship Promise: "Assistance" vs. "Guaranteed" This is the most crucial factor. Almost every platform promises "placement assistance," but this can be a vague term, often meaning little more than resume workshops or forwarding your CV. What to look for: A written guarantee of an internship. This is a non-negotiable sign that the platform is confident in its curriculum and is invested in your outcome. The Gold Standard: Platforms like AiWebix take this a step further by offering a guaranteed paid internship. This is the ultimate proof of a program's value, as it provides not only priceless experience but also de-risks your financial investment.

Learning software development today is both easier and more overwhelming than ever. There are thousands of tools, platforms, tutorials, and courses online, but how do you know which one’s actually worth your time? If you're just starting out or looking to level up professionally, figuring out where to begin can feel like trying to learn coding in a wind tunnel: loud, chaotic, and full of mixed signals. I was in the same position not long ago. As a self-taught developer preparing for a full-time job in backend engineering, I knew I needed structure, but also flexibility.

When it comes to Japan’s kei trucks and vans, the Honda Acty has long been one of the most versatile and dependable vehicles in its category. First introduced in 1977, the Acty line became synonymous with reliability and practicality, often serving as the backbone for small businesses, farmers, and delivery services across Japan. While earlier models like the HA3 and HA4 built a reputation for rugged efficiency, the HA8 and HA9 models, produced between 2009 and 2022, represented a more modern, refined evolution of Honda’s kei truck design. These models not only complied with stricter emissions standards but also delivered meaningful changes in performance, safety, and overall drivability.

Serverless architecture represents a paradigm shift in deploying and managing applications. This approach not only alters the way companies design solutions but also significantly redefines the cost structure in cloud services. Serverless computing, contrary to what the name suggests, does not eliminate servers but abstracts their management from the users. It is a cloud-computing execution model where the cloud provider dynamically manages the allocation and provisioning of infrastructure and accompanying resources. Essentially, developers can build and run applications and services without the overhead of managing the infrastructure typically associated with computing. This distribution of responsibilities can influence and potentially reduce software development time. Event-driven and S…  ( 22 min )

GitHub Home I still remember the bug that kept me up all night. A payment callback endpoint, when handling a rare, exceptional status code from a third-party payment gateway, had a .catch() that was accidentally omitted from a Promise chain. The result? No logs, no alerts, and the service itself didn't crash. It just "silently" failed. That user's order status was forever stuck on "processing," and we were completely unaware. It wasn't until a week later during a reconciliation that we discovered hundreds of these "silent orders," resulting in tens of thousands of dollars in losses. 💸 The lesson was painful. It made me realize that in software engineering, we probably spend less than 10% of our time on the happy path. The other 90% of the complexity comes from how to handle all sorts of e…  ( 9 min )

AI feels like magic until you get your first bill. When teams discuss whether to rent a general-purpose LLM (like GPT, Gemini, or Claude) or build their own smaller domain-specific model, the conversation often gets stuck on price tags and technical complexity. But there’s another critical detail that many articles gloss over: general LLMs don’t magically know your company’s data. If you want them to answer real product or order questions, you have to wire them into your systems. This blog takes a clear look at both paths, using the same example of retail chatbot answering "Where’s my order?"—to highlight the tradeoffs. At first glance, this feels like the easy button. You call GPT or Gemini’s API, pass in a customer question, and get a natural-language answer. But here’s the reality: GPT …  ( 7 min )

Everyone's talking about Google’s MAD privacy algorithm, but the real win is more signal from rare data without exposing anyone’s identity at scale. Most teams think privacy means dumber models. It doesn’t. The trick is how you weight each data point. MAD flips the old rule of “treat everything the same.” It shares the spotlight so rare but important patterns stand out. Common events still count, but they don’t drown the edge cases. You get richer insights and stronger privacy at the same time. Think of it as turning up the mic on quiet truths, without naming the speaker. Example. A fraud team trains on 10 million records. The rare chargeback pattern shows up in 0.2% of cases. With spotlight-style weighting, recall on rare fraud jumps 34% and false negatives drop 22%. Privacy stays intact because no single user is exposed or traced. ↓ How to apply this fast. • Map your rare events or long-tail segments. • Set a clear privacy budget and logging rules. • Reweight contributions so rare, high-value signals have a louder voice. • A/B test against your baseline and ship only if lift beats privacy cost. ↳ If you cannot explain the privacy setting in one sentence, it is too complex. ⚡ Faster detection of edge cases. ⚡ Less bias toward the average user. ⚡ More trust from customers and regulators.

If you’ve tried building with today’s best AI models, you’ve felt it: tokens aren’t free. Powerful models can turn a rough idea into working code in minutes, yet the meter is always running—and the best rate limits are often behind paywalls. That tension is shaping who gets to learn, experiment, and ship with AI. The money part nobody likes to talk about Why this matters right now But access is uneven A practical playbook to build without bill shock Match the model to the task. Explore with cost-efficient models; upgrade only when quality truly matters (e.g., gnarly refactors). Keep prompts lean. Shorten context, link files selectively, and summarize to control token growth. Batch and cache. Where available, batch or cache responses to cut per-token costs. Adopt an “agentic diff” workflow. Ask AI to propose diffs—not whole files—to reduce retries and output tokens. Explore cost-offset options. Some tools experiment with sponsored devtools that subsidize or offset token spend when you pick a stack recommendation during coding. It’s a promising way to let more people participate in vibe coding without upfront costs (e.g., what we’re piloting at CheaperCursor). If you’re curious about trying vibe coding without cost anxiety, you can test this sponsored-stack approach at https://www.cheapercursor.com —no pressure, just another path to build more and pay less. The upside of broader access Lowering the cost barrier isn’t only about saving money; it’s how we widen the funnel for new builders. Vibe coding lets beginners ship simple apps and lets pros automate the slog. When more people can afford to practice daily, you get better code, faster learning, and a healthier open-source ecosystem. That’s a win for everyone.  ( 7 min )

Three months ago, I left my job at PaloAlto Networks and started completely focusing on my own startup. It was not an easy decision for me. The job was very peaceful and flexible. But, building my own startup was always my dream and I can't hold it any more. Around 3 years back, my friend Sachin Neravath shared an idea of implementing price localization for digital products. We started it as a side project. We developed and released the product. Sachin quit his job and started concentrating completely on the product, that really worked. Within a short span of time we got good traction. Multiple payment providers reached out to us for integration and everything went well, we got many popular creators and some of the fastest growing SaaS companies as customers. During this time, we talked t…  ( 6 min )

Let's step beyond the scope of GDAL and explore the features of emscripten. In computing, a File System is a method for managing and accessing data in the form of files. Data is stored on a variety of hardware devices, each with its own way of accessing data. The file system abstracts the complexities of data management and access into a unified interface, allowing users to manage and access stored data without understanding the underlying physical device parameters. Different operating systems have developed various file systems over time—for example, Linux supports ext, ext2, etc.; Windows supports NTFS, FAT32, etc.; and macOS supports HFS+, APFS, etc. These are not entirely compatible with each other. To enable software to run across different UNIX-like operating systems, the IEEE devel…  ( 9 min )

Have you ever wondered what really happens when you type a URL in your browser and hit enter in a Laravel application? Behind the scenes, Laravel does a lot of work before returning the response you see. This process is called the Request Lifecycle — and understanding it can help you debug, optimize, and write cleaner code. Let’s break it down step by step (without overcomplicating it). Everything starts with public/index.php. This file is the entry point for every request. Think of it as Laravel’s “gatekeeper.” All requests — no matter what route you hit — will pass through this file first. Laravel has two kernels: HTTP Kernel → Handles web requests. Console Kernel → Handles Artisan commands. For browser requests, the HTTP Kernel takes charge. It loads important parts of the framework, li…  ( 7 min )

O que é? O Motor Fan L9110 é um módulo pequeno e de baixo custo muito utilizado em projetos de robótica diy, especialmente em projetos "bombeiros" visando conter pequenos incêndios. Ele atua como um intermediário entre um microcontrolador (no nosso caso, o arduino) e o motor do ventilador, permitindo que você controle tanto a velocidade de rotação da hélice quanto a direção. E isso se dá por causa do circuito L9110 que ele possui, constituído de duas pontes h. Ao aplicar uma tensão em um motor de qualquer uma das duas direções,o usuário é capaz de direcionar a rotação da hélice. Tudo isso graças ao circuito eletrônico da ponte H. Podemos ver que o módulo possui 4 pinos de conexão: VCC: conectamos este pino na tensão de alimentação do Arduino. No caso deste módulo, 5v. GND: terra. Conect…  ( 6 min )

Recently, I developed a somewhat experimental CLI parser library called Optique. While it has now been released up to version 0.2.0, I think it's an interesting idea worth sharing in this article. Optique was influenced by two very different libraries. One is Haskell's optparse-applicative library, which taught me that CLI parsers can be parser combinators, and that this approach is incredibly useful. The other is Zod, which TypeScript users are already familiar with. While I got the core idea from optparse-applicative, Haskell and TypeScript are such different languages that there are significant differences in how APIs are structured. So for API design, I referenced various validation libraries including Zod. Optique expresses what a CLI should look like by assembling small parsers and p…  ( 8 min )

When you're new to MongoDB, diving into the monitoring dashboard can feel like trying to read a foreign language. You're met with a sea of charts and numbers, but what do they all mean? What's good? What's bad? What demands immediate attention? This is a critical skill for anyone managing or building on MongoDB, from DBAs and DevOps engineers to developers. Understanding these metrics is the key to proactive performance tuning, efficient resource provisioning, and preventing outages before they happen. Over the years, I've spent a lot of time walking new team members, customers, and SREs through these charts. This article is my attempt to distill that knowledge and help you understand your MongoDB deployment's health a little better. Let's demystify some of the most important metrics you s…  ( 10 min )

In the ever-evolving landscape of API development tools, a David vs Goliath story is unfolding. Postman has long reigned supreme as the go-to API client, but a newcomer named Bruno is challenging the status quo with a fresh approach that's turning heads in the developer community. Is this open-source contender truly capable of disrupting Postman's dominance? Let's dive deep into what makes each platform unique and why developers are increasingly considering the switch. Bruno offers a completely free, open-source alternative that's gaining traction among privacy-conscious developers While Postman relies on cloud storage, Bruno keeps your sensitive API collections safely on your local device Git integration comes built-in with Bruno, making team collaboration seamless without subscription f…  ( 10 min )

Why are all gems now built in 1980? Bundler v2.7.0 had a change that went largely unnoticed: reproducible builds. See https://reproducible-builds.org/ Previously biulds were only reproducible if you set SOURCE_DATE_EPOCH in the env. Gems that relied on reproducible builds, like stone_checksums, wouldn't work without it and enforced it. But in bundler v2.7+ SOURCE_DATE_EPOCH is not required, so I've released stone_checksums v1.0.2, with support for both types. And now all ruby gems are built in the same second in 1980.  ( 5 min )

Question: Consider a rat placed at (0, 0) in a square matrix of order N * N. It has to reach the destination at (N – 1, N – 1). Find all possible paths that the rat can take to reach from source to destination. The directions in which the rat can move are ‘U'(up), ‘D'(down), ‘L’ (left), ‘R’ (right). Value 0 at a cell in the matrix represents that it is blocked and the rat cannot move to it while value 1 at a cell in the matrix represents that rat can travel through it. Note: In a path, no cell can be visited more than one time. Print the answer in lexicographical(sorted) order Examples: Example 1: Input: N = 4 m[][] = `{{1, 0, 0, 0}, {1, 1, 0, 1}, {1, 1, 0, 0}, {0, 1, 1, 1}}` Output: DDRDRR DRDDRR Explanation: The rat can reach the destination at (3, 3) from (0, 0…  ( 9 min )

Key Concepts Karat The measure of gold purity, expressed in parts per 24. The gold sovereign is a British gold coin with a specific gold content. Gold Content: 7.322 grams Gross Weight (including copper): 7.988 grams The fee charged by jewelers for crafting raw gold into jewelry. It includes the labor cost and design charges. The additional gold or material lost during the jewelry-making process. Jewelers often charge a wastage fee, which is added to the making charges. It refers to the incremental increase in worth or utility imparted to raw gold through processes such as refining, shaping, and crafting it into products. This value addition enhances the desirability and market price of the gold beyond its base commodity value. A certification issued by the Bureau of Indian Standards (BIS) that verifies the purity of gold. It ensures that the gold content is as claimed by the jeweler. 916 represents the purity Gold Jewellery Gold Coins/Bars It is offered by jewelers to help individuals accumulate gold over time. Returns are in the form of gold, not cash. These are government-issued securities that allow investors to invest in gold without physically owning it. These bonds are issued by the Reserve Bank of India (RBI) on behalf of the Government of India. The bond has a fixed tenure of 8 years with an option to exit after the 5th year on interest payment dates. SGBs offer a fixed interest rate of 2.5% per annum on the initial investment amount, payable semi-annually. The capital gains on redemption are tax-free. However, interest income is taxable as per the investor’s income tax slab. It is an ETF listed on stock exchanges. It allows investors to buy and sell units of gold in a dematerialized (demat) form, similar to shares. Each unit typically represents a fraction of physical gold (e.g., 1 gram or a certain percentage of gold). Stay Connected!

Humanity's growth over the last 200 years is undeniable, with advancements that have brought wealth and comfort to countless lives. However, this progress comes hand-in-hand with a growing problem: inequality. The gap between the richest and the poorest widens every day, and the global economic balance tilts further, concentrating power and privilege in the hands of a minority, the 1%. The vast majority, the 99%, are caught in a relentless race for resources and opportunities. Facing this, many turn to radical solutions, but I believe true change comes from within the system itself. My vision is to use the system's own tools against it. Not to destroy it, but to reshape it into something more just and accessible. The goal is clear: to make life difficult for the powerful and easier for tho…  ( 7 min )
